Interesting point on Johnny Law

[The Cincinnati Kid]

Anyone been slightly observant on the Ricin case in the US lately?
Got a bit lost in the Boston situation hogging all the news.
Anyhoo, to summarise briefly, Johnny Nutjob send a couple of 3 letters to congressman, senator etc. The letters have the deadly poison ricin in them and thus an enormous investigation commences.

Anyhoo, they caught the guy due to the FACT that within the letters was a certain signature and writing style and the FBI or whoever used this style to search twitter/farcebook etc etc to look for matches and found one.
Thus said nutjob was arrested.
If that wasn't facinating enough....turns out he was framed by his arch enemy (the Texas equivilent of Moriarty no doubt)
The real culprit had already anylised his writing style and forged it.

doubly facinating.
