I suspect that there are thousands of police officers in New York and elsewhere who spend their days policing "the projects" in large cities all over the country and manage to do it without shooting unarmed people. I guess they're just plain dumb and careless in your eyes, huh?
That is where you are wrong. There are parts of the city that police avoid. One obvious example is Baltimore. Police have stopped policing. This is the case all around the country.
Here in Phoenix, Arizona you used to see police cars all the time. Now they are no longer visible as if they have completely disappeared. They were always in parking lots hanging out. Now they are vacant.
It is obvious police have realized they are targets and have been told to hide from sight.
You can be all high and mighty and extract your pound of flesh from this officer but the net result is that police are no longer available the way they used to be. Just a fact!
