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

Q: Officer, did you see my client fleeing the scene?
A: No sir, but I subsequently observed a person matching the description of the offender running several blocks away.

Q: Officer, who provided this description?
A: The officer who responded to the scene.

Q: A fellow officer provided the description of this so-called offender.  Do you trust your fellow officers?
A: Yes sir, with my life.

Q: 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 your daily duties?
A: Yes sir, we do.

Q: And do you have a locker in that room?
A: Yes sir, I do.

Q: And do you have a lock on your locker?
A: Yes sir.

Q: 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 officers?

A: You see sir, we share the building with a court complex, and sometimes defense attorneys have been known to walk through that room.
