All these mass shootings were ended by someone shooting them. It's that vicious cycle argument, we NEED guns to STOP guns. Think about that. We don't NEED guns. If we took the most obvious and logical step, taking guns out of that equation, then there wouldn't be an equation to be balanced out. That is the end run here and it's pretty obvious. Repeal the 2nd amendment.
The problem is your logic doesn't work. France already has all of the laws you want and more and the perps that murdered 130 in Paris simply ignored those laws and in fact used them to their advantage as it took the police ages to get to the scene and the bad guys knew they were immune from the civilian population.
