Arrests are not necessary in the vast majority of situations police are called for, and recording technology is far superior to verbal testimony for serving our courts
EDIT: the ignorant people claiming average police officer does not deal with violent criminals have obviously never worked as a first responder. They deal with rape, suicide, murder, assault, domestic abuse, robbery, every week unless they're some small town cop in a gilded neighborhood.
The cops in St. Louis, Chicago, Baltimore, NYC, etc, see it every single day.
I hear a lot of suggestions by people have have never done the job. People making spurious claims about what police do and don't deal with on a daily basis.
I would never support female cops without firearms, for example. A grown man can easily overpower any woman, period. Especially when they are tweaked out on drugs.
Cops carry a gun because they have less than 6 seconds to respond to deadly situations that can save lives.
You have to solve both sides of the gun equation for a disarm to work in the US, because violent criminals have very easy access to guns here. If you remove guns from the cops without doing so on the otherside, you're going to unleash hell.
