Back in the days of Rockstar's L.A. Noire, the Los Angeles Police Department was a haven for corruption, where bribery, cover-ups, and extortion were common practices. Thank goodness detective Cole Phelps got that all cleaned up.

This is official L.A. Noire trailer number three, just released by Rockstar, giving us a glimpse at some of the struggles our hero Cole Phelps will have to deal with on the other side of the badge. There's far too much money floating around 1940's Los Angeles, and it's all-too-easy for officers of the law to stray from their duty in the face of fortune.

Not Cole Phelps. He's as clean as they come, a real straight-shooter with an eye for justice. It helps if you imagine this all being read in a 1940's radio announcer voice.

Can you resist temptation when L.A. Noire hits the Xbox 360 and PlayStation 3 on May 17?
