Shouldn't somebody call security?

In many companies dealing with sensitive issues or lots of money, when someone is fired security is immediately called to escort the firee off of the premises. No last chance to steal or damage stuff, spread rumors, or hack into the computers.

So why is a lame-duck Congress allowed to do one more month's worth of damage, in the form of more pork-laden, democracy-destroying legislation, before being sent home to the voters who rejected them?
