Here in Texas, it's legal to *non-lethally* booby-trap property. Don't know what the laws are where this took place. When I first read this my opinion was that this was stupid, a flash-bang grenade would've posed a great chance of setting the truck on fire. But this obviously wasn't a grenade, it must have been a smaller firework with a similar effect. Not to mention, the guy wasn't so stunned he couldn't get into the getaway car.
