I noticed that too. Not how a well trained professional would hold himself. I have been a sports shooter for years, never should your finger touch the trigger unless you're aiming to shoot.

My dad had been trained as a sniper in CAF. He used to say: "there's no need for more than 1 bullet". I thus know how to handle a firearm since being 8 yo. Those guys are parading with assault weapons. They probably use them to shred pumpkins on weekends.
