Dont we have the right to be safe and not live in fear?
Yes, why do you fear a firearm in the possession of a good person? Most feel safer in this position.
Banks get robbed, the hire a security guard to protect them.
Planes get hijacked, we hire Air Marshals to protect them.
Police officers have firearms, and if you were surrounded by a gang in Baltimore, would you not be happy to see an officer? Would you feel more safe? Why? Because they can protect you. They have the TOOLS to do so.
