Current teacher here. When there are shortages of teachers, states find ways around those degrees. I have a bachelor's and a master's, and neither are in education. When I decided to make the jump, it was through a alternate certification program, which I have heard since then referred to as "certification mills". My wife, also a teacher, works with others who have come through such programs and gripes about how little they get about actual teaching from the programs.
So, go ahead, short sighted mulitgraincracker (is that a racist username, BTW?) set educational requirements for a job that people aren't going to anyway because of low pay, long hours, massive lack of respect, frequent harassment and sometimes assault, and watch the high quality applicants line up
Or maybe stop lumping all cops into the same negative group, treat them as individuals, not a collective, encourage the good ones, work to weed out the bad ones, stop teaching specific groups of people that cops are their enemy, out to get them, and to make every encounter with police a hostile one. Just a thought.
