There is no such thing as an "MP5 uzi".

I guess you're right, but they look like uzis enough for me, and is otherwise a compact submachine gun.

What I'm referring to specifically is this, I believe: http://en.wikipedia.org/wiki/Heckler_%26_Koch_MP5

Do the Mp5 Uzi's protect against people that legitimatly have access, or how about a repairman? or during a fire drill - all doors open?

Presumably, everyone on the entire campus is trusted to be there, with increasing layers of security. There are guards posted at all entrances to the campus, where I have to present a badge + window sticker to get on. Once on campus and parked, a swipe card gets me into the building, where I am presented with an X-Ray machine for my belongings and a metal detector that I have to walk through for entrance.

If I am taking any property on or off campus, I have to also present a property pass signed by someone with the authorization to allow that activity.

Admittedly, I could probably sneak a flash drive on if I were so inclined, but that's probably why they do background checks on people before they're given badges and swipe cards and all that.
