i was one...
first off, this game is the tits. After going rogue mid mission cuz i was high and distracted, I decided that a few thugs on the corner needed a knifing. After one of them came at me with a pistol, i disarmed him, and quickly killed his posse. After 5-8 minutes of running from the police with 3 stars, i seem to shake'em via a bridge walkway. I find a pack of people and slowly walk when all of a sudden flying up from the side of the bridge...2 Helicopters!
full stars and soon death.
