Personally, I think there is a place for some size as a cop. It helps chill out a situation.
I don't think even smaller guys should be cops. It leads to the need/use of more deadly force when a cops mere Presence is not enough to be somewhat intimidating/imposing. Ive seen this happen, and it's bad for the officer, public and the offender. ALL the "equal opportunity" biz in this country is pure fantasy. People are not equal in every way. And pretending is BS. Hell yes, there are women who are much stronger than most guys, but it's a small number.
