Did 'silencer' make a difference in Virginia Beach carnage?

It’s the nightmare scenario that gun-control advocates have warned about amid efforts in recent years to ease restrictions on the devices, which they say can help shooters escape detection and inflict more carnage.But gun-rights advocates and most law enforcement experts say DeWayne Craddock’s use of a suppressor likely had no bearing on his ability to kill so many people in so little time Friday.Virginia is among 42 states that allow residents to purchase and possess suppressors, though some cities and towns — including Virginia Beach — prohibit them.Known colloquially as a “silencer,” a suppressor was attached to the .45-caliber handgun that police say the shooter used to kill a dozen people on three floors of the building where he worked before police closed in and, after a protracted gunbattle, fatally shot him.That could at least partially explain why survivors of the attack said they were caught off guard and initially puzzled by what was happening.
