It is hard to deny that policemen will cause a worse result because of abusing their guns in some missions, and such a fact leads susceptible people to generate the opinion that policemen should not use any lethal weapon to control violence. However, such a statement suffers from both logical and factual inaccuracies, and it should be examined in detail. As far as feasibility, equality and economics are concerned, I strongly hold that guns are necessary tools for police to enforce the state of violence and crime.
