Get a four star wanted level, then start a mission to get the achievement.

Get on the airport runway with a car, then get out. This will instantly give you a four star wanted level. Then, run or drive to the end of the runway to get the achievement.

Start picking off cops one by one. Your wanted level will rise as more of them are killed. After you get a four star wanted level, get in a vehicle, and drive into the subway tunnel. Once you leave the flashing wanted circle and your wanted level disappears, you will get the achievement.
