I read the good guys are looking for a 12 member sleeper cell related to the Boston bombers. And a couple guys in somewhereistan are already under arrest.

FBI also says the Boston type attack is the future of terrorism against the US. I am only surprised it took this long. After 9/11, suicide bombings and IEDs where almost a foregone fearful conclusion in my mind.

I know a guy...a bio scientist guy. Says there is a crap ton of sniffer technology that most don't know about. We'll probably see a lot more if that, probably with public alarms when bad stuff is sensed by detectors in public places.
