Most people get cop, grind it for a day or two, and go back to being civilian anyways because lets be honest, sometimes being a cop isn't all it's worked up to be. People will log on and kill everyone because they don't know how the server quite works yet. During this time they get jailed a lot so they see cops as powerful things. First thing they wanna do is become a cop so they get the 30 hours and apply. By this time they learn how the server works so they grind cops for a minimal amount of time and go back to planting drugs because drugs make more money. Cop is more of a "Hey guys I ranked up" sort of thing. I think the current requirements are fine the way they are.
