All the high-powered rounds did was puncture the tank and shoot gas into open air, which is going to be far too diluted to ignite at that point.
A bullet is not going to ignite a propane tank. The fuel/air mixture will be way off as soon as the tank is punctured and the vapor escapes into open air. It really would be a 1 in a million occurance.
And if you're giving odds that long, the odds of the LAPD setting the ****er ablaze after saying "Hey, lets burn this building down" are FAR greater than the odds of a bullet igniting the propane or even the a flash/bang grenade lighting the propane fumes.
What probably happened is that the tear gas cannister ignited an inert substance like a couch. What almost, 100% did NOT happen was the propane tank was ignited ignited by stray gunfire.
A stray bullet wouldn't have had to ignite the tank. All it would have had to do was pierce it. How long to you think it takes to vent a 500 gallon tank, for instance, through a bullet hole? How far will the gas be ejected before it safely dissipates, and what are the concentration levels at various distances from the hole? Where was the tank relative to the cabin? Or was it even above ground at all? I don't know. I do doubt, however, that Random Joe Cop was in charge of the entire operation and happened to be near an open mic when he decided to burn down the cabin two hours before it happened.
