MrAmon, just some food for thought:
1. What happens when the cop IS the bad guy
2. Have You noticed that most mass shootings and terrorist attacks take place in "gun free" zones (e.g. schools etc.)
3. Have You noticed the fact that criminals do not obey the law (that's why they're called criminals) and get their guns in an illegal way to begin with?
4. Have You noticed the number of innocent civilians killed by cops?

Do You really live in 2016 or are you riding a unicorn in fantasyland somewhere?
