1.In the scene when Burns and the SWAT team are crossing the escalator the guy from T2 stops the escalator.
2.The first officer say's "Hey turn that back on, What do I look like to you" the T2 guy pulls a Glock and reply's "A sitting duck" and shoots the officer in the head. The officer falls, and the T2 guy ducks behind a makeshift table (A barrel with a toolbox on it.
3.Watch the TOOLBOX!!!
4.The next officer shoots his M-16 missing the T2 guy but hitting the toolbox leaving a small cluster of 12 gauge pellet holes in it's side.
(Not a large cluster of .306 rounds like an M-16 fires!!!)
