This isn't criticism of the method or execution of a punk. This is a matter of something far more important -- extracting crucial information -- like a possible ACTIVE NETWORK. (although, we can expect this guy's home, computer and FB pages to be contaminated by The Regime as usual.)
THIS is why terrorists in the ME were not summarily executed (back in the sane days); They were pumped for valuable info that prevents other extreme loss of life.
And you have confidence that the current FBI would be willing/able to extract/use the information? I have a bridge ...
