Alex Caine knows well the world of outlaw bikers.

The retired criminal investigator spent years of his life infiltrating biker gangs and spilling their secrets to law enforcement.

At different times, the Quebec-born Caine has lived among Hells Angels and Bandidos, repeatedly worn a wire and helped to bring down dozens of bikers on criminal charges.

In the 1980s, Caine infiltrated a Bandidos chapter in Bellingham, Wash., working his way up from a prospect -- the equivalent of being an intern in the biker world -- to the position of secretary treasurer at the national level.

He even got an official membership card that warns that Bandidos are "the people our parents warned us about."
