SWAT teams were slowly but surely evacuating all students

When the h*ll is one of these highly trained and highly paid units actually going to get into a fire fight with one of these shooters?

What the h*ll is the use of these paramilitary uLEO's?

North Hollywood Bank Robbery was the last time I remember hearing them do it.

There may be an exception somewhere, but the general rule is that the shooters take themselves out when they are confronted by cops. So the cops never need to get into a firefight. They just need to get to where they can confront the perp.
