Hint: Finding criminals:

Hint: Getting badge points:
if you lose a lot of badge points you will become a civilian. Bust a few druggies until you get a 9mm or any weapon. Hoster that weapon. Then. go up to any man and grapple him. Do not hit him. Arrest him. Most of the time he will have some drugs. Turn them in. If you keep doing this, you will get a lot of drugs. Turn them in and you should get on the force.
