Having used CS, CN, HC grenades and distraction devices inside various purpose-built, abandoned and makeshift structures, the only one of the four listed above which I have ever seen start a fire is a distraction device (you all know them as "stun" grenades) which ignited a frayed burlap cloth wall frame in a makeshift training facility.

No, gas didn't do this. Neither did distraction devices. Those who have heard the audio of the firefights, do you remember hearing explosions? None of the reporters on scene behind the perimeter control have reported hearing explosions or anything other than weapons fire. A stun grenade is very distinctive and the sound carries as far as the sound of gunfire.

They used TH incendiaries - burners. In fact, they used seven of them, strategically-placed so as to leave zero escape routes. Of course they wanted Dorner dead. Deadly force was authorized to stop his rampage. Fire is deadly (and painful) - there you go - deadly force. Everybody wins.

Don't fuck with the po-lice because you'll be burned alive. I thought Waco already taught us this? Why are people surprised that the Filth would stoop so low as to trap a man in a house and watch him burn to death?
