A defense attorney was cross-examining a police officer during a felony trial.  It went like this:
 

Attourney:	Officer, did you see my client fleeing the scene?
Officer:	No sir, but I subsequently observed a person matching the description of the offender running several blocks away.
Attourney:	Officer, who provided this description?
Officer:	The officer who responded to the scene.
Attourney:	A fellow officer provided the description of this so-called offender.  Do you trust your fellow officers?
Officer:	Yes sir, with my life.
Attourney:	With your life?  Let me ask you this then officer - do you have a locker room in the police station - a room where you change your clothes in preparation for you daily duties?
Officer:	Yes sir, we do.
Attourney:	And do you have a locker in that room?
Officer:	Yes sir, I do.
Attourney:	And do you have a lock on your locker?
Officer:	Yes sir.
Attourney:	Now why is it, officer, if you trust your fellow officers with your life, that you find it necessary to lock your locker in a room you share with those same officers?
Officer:	You see sir, we share the building with a court complex, and sometimes lawyers have been known to walk through that room.
