You obviously have never been in or trained with law enforcement, never have been in stressful situations on a regular basis, put up with verbal/physical confrontations.
Considering the thousands of dangerous situations law enforcement deal with every single day, not too bad. Sure it can be improved but when you look at the big picture, law enforcement does a pretty darn good job. Do police make dumb mistakes, sure. Have you ever done anything stupid? How about the thousands of correct decisions law enforcement make every single day. Oh, the media very rarely cover this.
With regards to hospitals, by the time these people reach hospitals they have already dealt with law enforcement. Further, the ones that act up in the hospital, security is called or if security cannot handle it, outside law enforcement is called.
Recommendation for you! Quit watching police stories on the woke news channels and do a ride along with law enforcement. Who knows you just might learn something!
