Over 100 injured, over 80 dead in France attack

the only real solution is to kill a TON of the crazies at once to demoralize them,

Wait what? Isn't that exactly what is being done and is making "the crazies" go out and kill people? Also its not like they care about their life, most of them go prepared to die, I think the only way to demoralize them is not letting them kill people in the first place, catching them before they do anything and showing it on the media will make the rest of them think it twice since they wont be able to reach their goal.
