I've also thought about this, why most terrorists are so dumb.
I think it's because if they were smart, they would realize how hard it is to get away with it. This is literally one of the few criminal acts where no expenses will be spared in catching the perps.
Also, smart people tend to do something with their life, so they are less inclined to be attracted by terrorism.
Regarding Ross, once they figured out his name, it was over for him, USBKill or not.
