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.
