People do not become terrorists for fun. Most people would need a serious grievance against someone before they take the step. As for soulutions: Ask the British, they have some success getting rid of the terrorism in/from Northern Ireland. They did not get it by lining up a random selection of people and shoot them each time somebody blows a bomb. The Germans tried that tactic in occupied Europe during WW2. It didn't work then, it don't work now. Very few people will have trouble accepting "police" type actions agains terrorists, but random return violence is the sure path to more violence.
