Hillary Clinton’s critics slammed her for suggesting on Monday that an NRA-backed measure working its way through ​the House​ that eliminates restrictions on silencers would have made the Las Vegas shootings even deadlier.

“The crowd fled at the sound of gunshots,” she wrote on Twitter after a lone gunman used automatic weapons to kill at least 58 people and wound hundreds more at a concert on Sunday night.

“Imagine the deaths if the shooter had a silencer, which the NRA wants to make easier to get.”

She called on​ people to stand up to the National Rifle Association and defeat the bill.​

​”​Our grief isn’t enough. We can and must put politics aside, stand up to the NRA, and work together to try to stop this from happening again​,” the former Democratic presidential nominee wrote.​

​NRA spokeswoman Dana Loesch said silencers hardly make ​​​a difference in reducing the sound of gunfire. “Suppressors only reduce by a few decibels, still same decibel level as a jack hammer,” she wrote on ​her personal ​Twitter​ account.​

B​uck Sexton, a ​radio host and former CIA officer, said Clinton’s comments were “entirely irrelevant.”

​”​Appallingly stupid, and entirely irrelevant, Mrs Clinton She knows nothing about firearms, and even worse, she doesn’t care​,” he wrote on Twitter.​

The Hearing Protection Act, which is part of an omnibus Sportsmen’s Heritage and Recreational Enhancement Act, would ​remove restrictions over the use of silencers and treat them as regular firearms.

Supporters of the legislation say they’re needed to protect the hearing of gun owners, but opponents contend the sound of a gunshot alerts people to danger and helps police locate the shooter.
