"Sorry dude, I have no fucking idea what you're saying, plus you're a dick" is probably safer. They'd have to show you both understood and agreed with the action, but it's hard to prove that, especially if you started the conversation by not being a dick.
It's fun/scary reading the transcript and figuring out at what point you'd do what. If it were a random person IMing me from Iraq, I'd probably be friendly to start out.
The safest thing is to end the conversation before any criminal acts are discussed. I think it's also probably safer if you immediately switch to "you should report that to law enforcement, it sounds like a crime" vs. just "the fire, please die in it."
Did you just imagine doing something other than what AL did? Seems like "I can't imagine Adrian or someone else in his position not doing exactly the same thing" didn't last long :)
And yet a great, great many convicted felons do not report criminal contacts. I point to the number of convicted felons who go on to commit another felony in company of other criminals. Furthermore, I am led to believe that a culture of physical violence towards informants means that a felon who reports on other criminals is, frankly, asking for trouble. I wouldn't be surprised if the majority of felons do not habitually inform on each other.
They like to make an example of computer criminals. Locking up a marginal rapist, murderer, gang member, etc. doesn't serve any useful political purpose -- it just makes crime stats look worse.
