I had an interesting experience today about 1430. I was outside the building on a break, and two guys decided to have a little shoot-out. They weren't very good, though, lots of rounds expended, nobody got hit for a couple of seconds. I hid behind a concrete trash can, and made a radio call to lock down my building, but there was no way I could get back quickly, so I was essentially locking myself out (not such a great feeling).

One guy took a few rounds, and took off running toward the BART station, bleeding--- the other guy disappeared somewhere. I kept the building locked down until the helicopter moved off and the K-9 guy went away...

Sincere thanks for emphasizing the critical difference between cover and concealment. Ya never know when that will come in handy ;-)
