I didn't see where he displayed a gun and the officers opened fire, but I saw where they put the flash bang through the right rear window. After that the drivers side door opened and the nice doggy got to play for a while.
I liked a couple of the ideas e-mailed to Shepard Smith while this was going on....why not drive up an "armored" tow truck and just clear him out?....or why not bring in a Chinook helichopter to clamp onto the van,lift it and carry it to an enclosed secure lot, and just let him sit there?
Both would have cleared the freeway a lot quicker.
