How about we just close down all of the gun factories? Weld the doors shut. Then they won't be making so many millions of guns that wind up in crazy people's hands.
How bout you address the topic like an adult and not the limp dick jackass you are?
Okay, let's address the problem like adults. Poverty causes the majority of crime in the world, and the majority of the world's wealth is controlled by a very corrupt wealthy minority. With more wealth in the hands of the general worldwide population, it is more than likely that there will be less crime.
The global economy is based on energy- fuel and electricity for the production and transportation of goods. Cannabis hemp can provide the majority of the world's energy without the industry being controlled by a very corrupt wealthy minority. Legalizing marijuana will transfer the majority of the world's wealth through the free market to the working poor, raising the standard of living for all People on Earth, and lowering crime.
It won't be a utopia but it will be better than bombing Muslims over lies.
