1) Nope. You're wrong...
A flash suppressor is a device attached to a rifle to reduce the brilliant
muzzle flash which occurs upon firing. Muzzle flash is especially visible
at
night, and makes it easy to see the location of the shooter. It is caused
by
incandescence of the expanding gases produced by burning gunpowder.

The short "supressors" on my pre-ban AR-15s did nothing to hide flash,
especially at night. They did however keep that flash out of the shooters
eyes, allowing quicker recovery of sight picture in rapid fire events. I
don't doubt that the larger ones on sniper rifles hid flash but guess what -
those guns weren't banned cuz the don't have bayonet lugs.

2) Read the 9/11 report. They were trained to deal with overcoming people
with guns, knives, etc.

How do you train to overcome equally well trained plainclosed LEOs you
cannot ID using a box cutter?
