Someone who is shooting at cops is not a normal citizen. Creative use of fire/smoke is appropriate if it limits the death of more police officers. They didn't use "CBU" on the target...just applied force to an individual.

"Someone who is shooting at cops is not a normal citizen."?

Even "non-normal" citizens have Constitutional rights--which are NOT to be violated by government.

"Creative use of fire/smoke is appropriate if it limits the death of more police officers."

Sorry, but no. This is a level of violence/police methodology that is NOT unacceptable. The idea that "death of a police officer" must be prevented AT ALL COSTS is bullsh*t, and leads directly to government tyranny.
