Zodiac 2007
But who actually cracked the code? A married couple who like puzzles. So what's that tell us about the Zodiac? He's no expert.Right. It's just a simple substitution code like the one that we used to do as boyscouts. "A" is one, "B" is two. We weren't all boy scouts, Robert. Well, it's not that hard. You just gotto know where to start. In the first cipher... You actually carry that around with you? Why?No reason. What's the most common double consonantin the English language? Consonant? The double "L."Double "L." And what's the one word that we knowthat he'll use in here, at least once? "Kill."Right, "kill." So the Hardens start looking for doublesymbols, which they find here, here, and here. Each with the sametwo symbols preceding them. So now they've gota repeating four-letter word ending with two symbols that they assumestand for "L." And since they think the whole word is"kill" then... Then you got your "K," you got your "I,"and you're on your way. But how do you go from "A" is one and"B" is two to figuring out this whole code? Well, same way I did.You go to the library

But who actually cracked the code
00:00:04.005 --> 00:00:06.003
A married couple who like puzzles
00:00:06.038 --> 00:00:08.216
So what's that tell us about the Zodiac
00:00:08.003 --> 00:00:10.003
He's no expert Right
00:00:10.039 --> 00:00:11.766
It's just a simple substitution code
00:00:11.085 --> 00:00:14.014
like the one that we used to do as boy scouts
00:00:14.023 --> 00:00:15.089
A is one B is two
00:00:15.098 --> 00:00:17.476
We weren't all boy scouts Robert
00:00:17.056 --> 00:00:20.086
Well it's not that hard You just got to know where to start
00:00:20.094 --> 00:00:22.057
In the first cipher
00:00:22.065 --> 00:00:24.236
You actually carry that around with you
00:00:24.032 --> 00:00:26.078
Why No reason
00:00:26.086 --> 00:00:30.012
What's the most common double consonant in the English language
00:00:30.002 --> 00:00:31.045
Consonant
00:00:31.053 --> 00:00:33.016
The double L Double L
00:00:33.024 --> 00:00:36.786
And what's the one word that we know that he'll use in here at least once
00:00:36.087 --> 00:00:37.092
Kill Right kill
00:00:37.092 --> 00:00:39.916
So the Hardens start looking for double symbols
00:00:40.000 --> 00:00:41.008
which they find here here and here
00:00:41.088 --> 00:00:44.034
Each with the same two symbols preceding them
00:00:44.042 --> 00:00:46.336
So now they've got a repeating four letter word
00:00:46.042 --> 00:00:48.506
ending with two symbols that they assume stand for L
00:00:48.059 --> 00:00:50.176
And since they think the whole word is kill then
00:00:50.026 --> 00:00:53.041
Then you got your K you got your I and you're on your way
00:00:53.047 --> 00:00:55.306
But how do you go from A is one and B is two
00:00:55.039 --> 00:00:57.002
to figuring out this whole code
00:00:57.014 --> 00:00:59.081
Well same way I did You go to the library
