When people think of militarization of police, they may get scared due to the equipment that is being used by the local police. In this case, the equipment would include tanks, military weapons like assault rifles and possibly machine guns. These are used by the SWAT when there is a very dangerous situation. The police department that would use these things would need to be very trained so that they can fully understand how to use these equipment. They should also know when to use them.
They would not be needed in every situation. Society would benefit from the militarization of police during certain situations like a hostage situation or terrorist attack. When this occurs, this type of force would be needed, but not in all cases.
