One act of mercy doesn't wash away the bad. Most criminals don't commit crimes for 99% of their day. Cops also change their behavior when being filmed. Far less likely to brutalized someone as shown by complaints dropping 50% when they have body cameras.
Don't worry thethe, I got some real heinous stories coming. There's a sheriff in Louisiana who literally just advocated against prison reform that would let a few non violent inmates out of prison a few months early because they need the slave labor to wash their cars and cook their meals to save money. I **** you not.
