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.
The vast majority of police do not need guns.

Can you back this up? Statistics I've seen do not support your claim, and put violent crimes under 5% of police investigations.
To put 5% in more extreme terms: would you play Russian roulette with a 20 chamber revolver and one bullet?
Each interaction for police is like pulling the trigger in that hypothetical game of Russian roulette. This is why the absolute numbers are actually very important.
