The fact of the matter is, most normal Canadians have no clue how rough and ugly the underbelly of society is. I certainly didn't when I joined. Occasionally, policing is horrific to watch...... it's not always civilized. Alpha males are required to keep things in order. 

Not every suspect is a university educated person having a property dispute with a neighbor. Most bad guys are, in fact, really bad guys, that do stuff beyond comprehension or explanation. Every walked past the dead body of two little girls with smashed-in heads so you could arrest their father? I have. Every have to wrestle with a 250 pound 6'2" schizophrenic in a kitchen, so he would stop beating his mother? I have.

Occasionally, of course, a cop goes too far, however, there are mechanisms to deal with that.

Bottom line.....fill a major department with nothing but hipsters and female officers and let me know how that works out.....I'll stick with the Alpha's
