We got bombed by Saudis, the WTC, bombed once and then planes flew into it. We never retaliated against Saudia Arabia, instead we went for Afghanistan and Iraq. Now we got bombed by Chechnyians and we won't retaliate against them either because they are inside Russia.
These asymmetrical attacks are something else, you can't go after the perps' countries of origin necessarily.
I'm advocating that we learn to recognize psychopaths, database their predator asses very overtly with their pictures up on the internet and all that. I know one, got busted for felony sex with a minor and got his picture on the internet via megans list. He is greatly suppressed in his activities and has to sit around all the time trying to tell people how he is innocent just like all the lying psychopaths do that are in jails.
The older Brother recent bomber is very much fitting the psychopath profile, if his little bitch ass was identified as same, all the people that were influenced/beaten/murdered by knife/blown up by him wouldn't have even been with the guy at all. He apparently did a triple homicide before, that wouldn't happen if people were warned..
Radical Islam is very dependent on using psychopaths to further it's aims in the West, we could hamper it by diagnosis at their first offense of any kind and putting that information out where people, non radical Islamists included, could be warned. Diagnosis by brain scans is about 100% accurate.
