lock down?

MTSU was on lock-down today.  Local police, Homeland Security and the FBI were all involved.

Here's a link to info about it from The Tennesseean.  Looks like in the last hour they arrested the only suspect, who they think acted alone.  

Awful.  I know it's too early for details or to know what's going on, but if it's as bad as it potentially could have been, I'm glad for the swift action.  

I'm happy with Blue Raiders flying below the radar.
