You ever watch a pair of young lions get their first kill? Not much dignity to it. The lions maim but don't finish the job. They play around with the prey half expecting the creature to spring back to life. Then the mother comes in and does what is right.
These liquored up pigs were set on blood from the very start. This man was prey to be abused and experimented on. The flash bang was cute. That was the tell that this poor man was done for. Set the dog on him just for kicks, irony being if the dog was more trained than these pigs the man may still be alive. If these green cops had bayonets on their rifles they would have used them to...
All in all a murder plain as day. Shot in the back, run down like an animal, toyed with and killed in the sorriest way possible. I wouldn't be surprised if these pigs took a trophy shot kill to end the day. 3 pigs smiling on one knee next to their murdered victim with the scalp being pulled back in one of the hooves. They climb down those rocks giving themselves high fives recounting their good shoot.
