Animal with a Gun

The hosts try to work out where "10-4" and "Roger" come from.

“Peter Jackson would edit it down to a tight 16 hours.” (15:34)

Questions

Where do "10-4" and "Roger" (for "understood") come from? (01:05)

Our guess
Military or police radio codes from World War II, with "Roger" from Morse code's "R" for received.
Reveal the answer
The answer
"10-4" is one of the 10-codes created by the Illinois State Police's communications director Charles Hopper between 1937 and 1940 for police radio. "Roger" is from the WWII phonetic alphabet for R ("received"), which came from the Morse habit of replying with the letter R.
Verdict right

[00:00] Speaking of getting news from fake sources, do you guys want to do an undegoogleable?
[00:05] Sure.
[00:06] Can we do an undegoogleables?
[00:19] That was the play of it.
[00:21] Super excited.
[00:22] You told us we had to, sir.
[00:24] You said we signed up for it.
[00:27] In the end, it's going to be better and more true than Google can give you.
[00:33] Jason, I think it's time for an undegoogleable.
[00:37] What do you got for us this week? How can I help you?
[00:42] I mean, you have helped me so many ways throughout my life,
[00:46] and the fact that you're willing to help me more is so appreciated.
[00:50] Okay, here's one for you.
[00:52] So, you hear in the movies a lot, or on, I guess basically the movies.
[00:57] It's the only place I hear it.
[00:59] People are talking on the walkie-talkies, or the CBs,
[01:02] and they're saying like, 10-4.
[01:05] Gotcha.
[01:06] Or Roger means the same thing, basically.
[01:09] Like, heard.
[01:13] In other parlance, people say over or over and out,
[01:17] and that seems much more direct to me than Roger or 10-4, which are...
[01:23] Roger, Roger.
[01:25] What's with Victor, Victor?
[01:27] What's with Victor, Victor?
[01:32] You guys have any ideas on what?
[01:37] Well, I mean, so 10-4 just seemed like just off a list of codes,
[01:42] like for truckers or, you know...
[01:44] Ah, it feels military to me.
[01:46] Or maybe, yeah, or military.
[01:48] But it just seemed like it was a list of codes that you would just say
[01:52] for different, you know, just whatever.
[01:56] Confirmation, or, you know...
[01:59] But why would you want a code for heard?
[02:03] Right.
[02:05] Because you're like military, and you need code for everything.
[02:07] I guess, yeah.
[02:08] And yeah, so you don't want people tapping your conversation or whatever?
[02:11] I mean, it's not that...
[02:13] It's not like it's a brilliant cipher.
[02:21] What are the 10th and the 4th letters of the alphabet?
[02:26] Well, D is the 4th.
[02:28] Yeah.
[02:29] So it's not like, okay, or something like that.
[02:32] Right.
[02:33] It's a simple substitution, but maybe it's a...
[02:38] Yeah, 10 is J, so yeah, not very helpful at all.
[02:41] JD.
[02:42] Lawyer's in the house.
[02:44] JD.
[02:47] And then Roger.
[02:48] Roger has to be like an alternate of right or...
[02:54] I don't know.
[02:55] Like...
[02:56] What's in the...
[02:59] What's in the...
[03:01] Not the phonetic.
[03:02] Yeah, like the NATO phonetic.
[03:03] It's Romeo.
[03:04] NATO phonetic, yeah.
[03:05] What's R is for repossess or something?
[03:10] It's Romeo.
[03:13] Romeo.
[03:14] But maybe pre-NATO, it was Roger, because that's way more American than Romeo.
[03:20] Rem.
[03:24] That's true.
[03:25] So maybe, but still, then why R?
[03:28] Why is R like...
[03:30] Got it.
[03:31] Got it.
[03:32] Maybe there was a guy who just always understood what was going on in the video.
[03:41] And his name was Roger.
[03:42] And his name was Roger.
[03:43] But we're thinking these are all...
[03:47] I mean, yeah, it seems very obvious that most of these are military-derived, right?
[03:52] I always think that.
[03:55] Because they're going to be at the forefront of communication like this, where it's out
[04:00] in the field and crackly, staticky radios, and you need to be as clear as possible in
[04:07] your communication.
[04:09] And I'm like, police as well.
[04:11] Sure.
[04:12] But I don't know if that's...
[04:13] I guess I would think that those technologies are going to come to the military first.
[04:19] Yeah, I just assumed that police are all former military.
[04:22] Right.
[04:23] I mean, that's how the stuff seems to work.
[04:26] Your riot gear starts in the military, and then it trickles down to your local police
[04:31] forces, the tanks and stuff.
[04:34] I mean, that's just logical.
[04:36] That's just the way you would want to secure a neighborhood.
[04:41] Right.
[04:42] Well, so we're assuming that these things are all radio and not byproducts of like
[04:49] Morse code or something.
[04:51] Oh, that's a good point.
[04:52] Yeah.
[04:55] 10 seems like a lot of times to hate.
[04:57] 10 seems like a lot of hashes.
[04:59] Yeah.
[05:00] I feel like with the Morse code, though, I feel like there's...
[05:05] It's what's going to be much more clear.
[05:14] He said what?
[05:20] Every response is longer than the original message.
[05:23] Right.
[05:24] Excellent.
[05:27] I feel like with Morse code, though, it's the written word.
[05:33] It's not going to be as confusing.
[05:36] I feel like assuming that their error rates are low, I guess...
[05:43] Probably.
[05:44] But I'm sure they still punctuated the end of a message somehow.
[05:48] Sure.
[05:49] Yeah.
[05:50] Just like with the telegram, you would say stop or whatever.
[05:54] Yeah.
[05:55] And then you would want some sort of way to relay back to the person on the
[06:04] other end like received your whole thing.
[06:08] Maybe that's what Roger is, is received.
[06:10] Yeah.
[06:12] I'm guessing so.
[06:13] Good call.
[06:16] And...
[06:19] All right.
[06:20] Good.
[06:21] I'm glad we worked that out.
[06:22] Yeah.
[06:23] I like that one.
[06:24] Yeah.
[06:25] I guess at least the 10-4, I feel like that that was probably part of a larger list of
[06:30] common responses for a little disambiguation.
[06:35] And so time-wise, we're thinking this is post-radio, post-transistor, so the 50s were
[06:45] starting to do this stuff?
[06:48] 40s?
[06:49] Yeah.
[06:50] Probably World War II, I would have thought.
[06:54] Yeah.
[06:55] That's what I'm thinking.
[06:56] But I mean, I feel like they had good reviews and...
[07:00] Well, they had Morse code and telegraph before that, right?
[07:04] Yeah.
[07:05] Yeah.
[07:08] But I feel like they're definitely rocking all of those technologies during World War II.
[07:14] Okay.
[07:15] But definitely like 20th century, early to mid-20th century.
[07:19] Yes.
[07:20] Okay.
[07:21] Yeah.
[07:22] Okay.
[07:23] Okay.
[07:25] And strictly American?
[07:27] Good question.
[07:31] Doesn't Roger mean something filthy in British?
[07:35] Yes.
[07:36] So probably not British.
[07:38] It's what Coalson hopes he's doing.
[07:44] But probably not.
[07:45] But probably not.
[07:46] Okay.
[07:50] Let's see.
[07:51] 10-4 is one of the so-called 10-codes or radio signals invented by the Association of Public
[07:59] Safety Communications Officials International.
[08:04] It is an affirmative signal, it means okay.
[08:08] The 10-codes are credited to the Illinois State Police Communication Director, Charles
[08:13] Hopper, who created them between 1937 and 1940 for using radio communication among cops.
[08:22] Nailed it, Joey.
[08:24] And we got the timeframe.
[08:25] Well, that seems pretty straightforward.
[08:28] The early thing that I'm getting on Roger is that Roger was phonetic for R, received
[08:33] and understood.
[08:34] Okay.
[08:35] Cool.
[08:36] Okay.
[08:37] So here's Popular Mechanics, which is probably a little bit more trustworthy.
[08:41] The use of Roger as a confirmation has roots that go back even further than 1957.
[08:49] Let's see.
[08:51] Roger comes from a phonetic alphabet used by military and aviation personnel during World
[08:54] War II.
[08:55] So same deal.
[08:57] In the Morse code days when sending long messages should be arduous, a useful shorthand was
[09:02] to respond with single meaningful letters.
[09:07] So responding to a message with letter R, for example, simply let the sender know the message
[09:11] had been received.
[09:14] When two-way radio came along, the shorthand continued, but with the word Roger instead
[09:18] of R itself.
[09:21] So back on the 10-4, when the technology was first being rolled out, there were limited
[09:30] channels.
[09:32] So they had to make their communications quick where other people wouldn't be able to use
[09:39] it.
[09:40] So they were using these codes just to communicate quicker.
[09:46] Yeah.
[09:49] So interestingly, 10-1 meant you are being received poorly.
[09:58] And 10-2 is the equivalent of Roger, I guess, which is you are being received clearly.
[10:07] And then 10-4 is understood, or I actually got it.
[10:11] 10-3 shut up.
[10:13] Yeah, exactly.
[10:15] Stop transmitting.
[10:16] So I like this one.
[10:18] So on Wikipedia, the 10 codes, the first one on the list is 10-max.
[10:24] And it means somebody is AWOL or a corrupt officer.
[10:28] Officers are not following orders.
[10:31] In subordination slash rogue officer.
[10:35] Seems like a wide range of responses would be elicited.
[10:41] For instance, 10-35 is alcohol violation.
[10:45] 10-34, riot.
[10:51] So the thing is, OK, so there is a 10-35 before 10-34, but I don't know.
[10:59] There's different.
[11:02] So the 10 codes, there's different standards, it looks like.
[11:07] So there's like the first ones in 1937, 39.
[11:11] Yeah, and there's just like, there's different, over time, there's different standards.
[11:19] But yeah, I've seen a lot of these.
[11:25] Like 10-91, prepare for inspection at this date and time.
[11:31] 10-83, half officer, somebody called the station by telephone.
[11:37] And then for some things, they like have subcategories like, so 10-91 can mean prepare for inspection.
[11:48] Or it can also mean, if you add a letter after it, animal in some state.
[11:55] For instance, a 10-91E is an animal bit somebody.
[12:01] So because they're apparently quickly became regional and jurisdictional differences, it
[12:08] really wasn't until Hurricane Katrina that 9-11 has gone away from these 10 codes and
[12:15] moved to just plain talk.
[12:17] So instead of yelling out, for instance, 10-36, 10-36, you just ask what time it was.
[12:24] OK, gotcha.
[12:28] Because 10-36, if you're like communicating with somebody from some other jurisdiction,
[12:33] meant like...
[12:34] I'm being murdered.
[12:36] Yeah, exactly.
[12:37] Animal with a gun.
[12:41] That's 10-01 in Boise, by the way.
[12:47] That's just like status quo in Boise.
[12:52] So these are the same idea as what we've also, you know, you've seen some of these before,
[13:01] but the penal codes used by different jurisdictions, like California, you know, well, 187 is for
[13:08] homicide.
[13:12] I think 420 might be something.
[13:14] 420 might be something, 311 is one of them.
[13:18] It was like for, I think the band was from, no, it was like public indecency or something
[13:30] because I think one of them was streaking or something.
[13:32] I think it was, they were from like Kansas or something like that, or Missouri or somewhere.
[13:41] All right.
[13:42] Cool.
[13:43] Thanks, dudes.
[13:44] Nailed it.
[13:45] Nailed it.
[13:46] Obviously.
[13:47] What was that guy's name?
[13:52] Dennis Hopper.
[13:53] No, that wasn't right.
[13:54] Isaiah Stewart.
[13:55] Where'd it go?
[14:01] Charles Hopper.
[14:03] Charles Hopper.
[14:04] What did the Hopper?
[14:08] Apparently 10-04 is like, or October 4th is the day to salute radio operators.
[14:13] Aha.
[14:14] Very nice.
[14:16] Of course, did also, those caught on in the CB community too.
[14:23] Certainly hearing a trucker say 10-4 was always, it was always at least in the movies.
[14:28] 10-4, good buddy.
[14:29] 10-4, good buddy.
[14:33] It feels natural when you say it, Hopper.
[14:35] Yeah.
[14:36] If they don't say that, I'll be sorely disappointed.
[14:41] They still use those in the long haul.
[14:46] Are they all on, do you think everybody's on TikTok now?
[14:51] They're just on a Waze.
[14:55] Do you think they communicate by dance now?
[14:57] I hope so.
[15:00] It's all interpretive dance.
[15:02] That's right.
[15:03] Yes.
[15:04] That's the way everything's going.
[15:06] We'll send Coalson to a truck stop for some.
[15:09] We'll send Coalson to a dance class, I think.
[15:11] Yeah.
[15:12] We'll send him to a truck stop to investigate in the middle of the night.
[15:14] See how that goes.
[15:17] Do some interpretive dance.
[15:18] See how it catches on.
[15:19] See how it goes for him.
[15:23] Put that on Facebook live.
[15:30] We should slap a GoPro to him and just, I just want to do like a day in the life.
[15:34] Wind him up and let him go.
[15:36] Yeah, exactly.
[15:37] I'd pay good money for that.
[15:41] Can we get Peter Jackson on this project?
[15:45] I think so.
[15:47] He's all over this project.
[15:51] Yeah.
[15:52] Peter Jackson would edit down to a mere 16 hours.
[15:57] To a tight 16.
[15:58] Tight 16.
