Walk Free Glitch

[Pigletdude]

Ok this glitch is fairly odd, first of all make your way to the Francis Nation airport, then get into the runway, you will automatically get 4 stars, then hjack a policeman's car and leg it out and when you finally get out of the wanted area you will get the achievements, but to get it to work you MUST walk in to the airport and runway and get the 4 star rating.
Weird, try it out.

Yea and this has been posted numerous and numerous times before about going on the airport runway and automatically getting a 4 star wanted level.
