How to unlock the Going Rogue achievement in Grand Theft Auto III - The Definitive Edition - Definitive Guide
Caramel, Cardinal
The Vigilante mission can be started by hitting 
while in a law enforcement vehicle such as the police Car, Enforcer or Rhino (tank).
For this achievement I found the police car the best on Portland early on. You’ll first want a load of uzi ammo (getting 20 hidden packages will get you one for free at your hideout). From there steal a police car and go after the criminals. Do drivebys on their cars or ram them until they get out. Just be careful if you drive by not to be too close in case their car explodes and takes you out with it. If your car is getting damaged you can actually exit the vehicle for up to 60 seconds so if passing the police station it may be worth stealing a new police car if yours is damaged.
The Enforcer is a good vehicle but can be a bit slow for this achievement so you may run out of time, particularly if you have a fast criminal. It could be used for the completion of the mission required for 100% though.
The FBI car has the advantage of being able to use the pay and spray to repair it, however it is hard to get one requiring a 5 star wanted level.
The Rhino is hard to obtain and is slow so isn’t recommended for this.
For 100% completion, you need to kill 20 criminals on each island but these don’t have to be consecutive. You will know you have completed this as you will have 6 bribes outside your hideouts.
