Do some police officers or police departments need a change, I am sure they do. Do all need a change, in my opinion NO. Isn't making a blanket statement/decision based on certain events and not taking all the other factors involved in police work the same as why racism & sexism are wrong?
This is not different then any other profession: are some doctors, lawyers, pro athletes, priests, constructions workers, actors, etc.. bad people, they sure are, should everyone associated with those professions be grouped together and need to be changed. So should all OBGYNs need to be changed because of criminals like the doctor who assaulted Andrew Yang's wife and many others?
I am all for improving this great country, but lets have serious conversations with concrete ideas and solutions. Things like defund the police, the takeover zones popping up in Seattle and Portland, rioting, attacking or killing cops, destroying public or private property are not solutions, and they also do not improve our country.
