Why didn't police keep the criminal when taking his photo?

Larry's class were on a field trip to their local police station where they saw
pictures tacked to a bulletin board of the 10 most wanted criminals.

One of the youngsters pointed to a picture and asked if it
really was the photo of a wanted person.

'Yes,' said the policeman. 'The detectives want very badly to capture him.

Larry asked,
"Why didn't you keep him when you took his picture ? "

Yeah, why didn't they?

That appealed to my sense of humour :)

I remember, as a kid, arguing about The Unknown Soldier, the national memorial. "Hey People! Why didn't you just find out this fellow's name before you buried him? Ya look pretty darn silly now, don't ya?"
