Your take is hilarious and based on fantasy. Want to make it harder to be a cop, absolutely, claiming that has anything to do with child predators is hilarious. Civil service exam, background check, drug test, physical fitness test, psychological exam, police academy that lasts 3-6 months depending on the state/department. If that isn't enough hurdles to stop someone who is simply looking for victims, then having a degree wouldn't be either. A GED also gets you a job at Chuck E Cheese or the local batting cages, for without all those hurdles and way more access to potential victims.
