Those who stand by idly while America does this to other people should remember that what we're inflicting on them will be inflicted on us tomorrow.
The US military used B2 bombers in Iraq. Do you expect these to be deployed in Seattle any time soon?
For crowd control?

>From a Pennsylvania State Police helicopter, Philadelphia Police Department Lt. Frank Powell proceeded to drop two one-pound bombs (which the police referred to as "entry devices") made of FBI-supplied Tovex, a dynamite substitute, targeting a fortified, bunker-like cubicle on the roof of the house. The resulting explosions ignited a fire from fuel for a gasoline-powered generator stored in the rooftop bunker. The fire spread and eventually destroyed approximately sixty-five nearby houses.
Still, this looks like an improvised explosive device was used by the police, and it's not an off-shot of the US military programs.
So my point still stands - just because something is deployed by the US military abroad does not mean it will be deployed at home. To suggest otherwise is to spread needless gloom and panic.
Maybe not necessarily in 100% of the cases but once something is manufactured it is likely that the manufacturer will look to expand its customer base. Hence (imo) the militarization of police across the US and indeed the world.
