It should be mandatory to arrest a police officer on the spot the same as you would any other civilian breaking the law.
It’s been awhile since I took criminal justice but I’ll try to rattle a few off the top of my head. Feel free to chime in with your additions or why you feel something I picked wouldn’t be appropriate for a charge.
Reckless endangerment
Vehicular assault
Assault with a deadly weapon
Brandishing a firearm
