She thinks silencers are like the movies.
It it would have suppressed about half his sound for about what 15 to 20 rounds? He was pretty far up and shooting in a noisy environment.
Not half, 35db for a gun that's 165db. So when you factor in the echo of the area it was pretty much worthless. Plus at fully automatic as reports say the guy modified his gun his silencer was not made to withstand that heat.
And there's differences in how a gun sounds up close and the bullet traveling, which a silencer does nothing for. Witnesses all said they heard it but assumed it was fireworks. Which most people surprised by gunfire say.
