She should have known this would go over like a ton of bricks!

Kirstie Alley is getting a lot of backlash for insinuating that mass shootings like the one in Las Vegas on Sunday night are often the consequence of people taking psychiatric drugs, but she's not backing down in the face of criticism.

"We have to solve the mystery of why there are no ‘shooters’ or almost 0 before the 1980s. I know one common denominator other than guns. One additional common denominator of ‘shooters’ is U.S.A.’s mass usage of psychiatric drugs. A % do have side effects of violence and suicide," she tweeted on Monday.

There is no evidence yet that Stephen Paddock, the shooter that killed 59 people and injured 500 others at the Route 91 Harvest Festival, was taking any kind of medication, but the famous Scientologist thinks it's a definite possibility that he was.

"Did you really just say that? Sit down. 58 people are dead,” ABC reporter Derek Shore tweeted at the actress in response.

The Cheers star held her ground, though.

"Yes I did say it. It happens tone a common denominator in shooters..one that didn’t exist before the ‘80s.. not my opinion. Statistic based," she added.

We half way expect Tom Cruise to come out of the woodwork and back her up!
