I forgot about something interesting that I ran across yesterday. If you are on the internet and you go to the LCPD page, there is a link to the LPCD database at the bottom. There's no spoilers I don't think, but a police record for every "badguy" character in the game, as well as a few who you wouldn't necessarily expect to find in there.
i have just finished all the Police side missions.....you can carry on with fighting the normal crimes for as long as you want i think,however i think the most wanted is restricted to 10 per island
i'll be sure to check out the LCPD page
