Seems to me that every organization has a Barney Fife. You know the type, a little too enthusiastic, and with a warped sense of priority and proportion.

That sort of guy makes a good sidekick and functionary as long as they are tightly supervised and kept away from anything that might cause harm.

The issue isn't so much a matter of a security guy going too far. It is a matter of who put him in a position where his lack of judgment was allowed to play out.
