Kirstie Alley's controversial Vegas shooting theory

Kirstie Alley has shared her own controversial view as to why a gunman opened fire at a Las Vegas music festival, killing 59 people and leaving over 500 injured.

Taking to Twitter, the 66-year-old actress suggested "mass usage of psychiatric drugs" is the "common denominator" when it comes to shooters in the US in the wake of the latest mass shooting.

Despite Kirstie having no medical background to support her claims, the Cheers star is a devout Scientologist, with the church holding strong views and being previously outspoken against the use of prescription medications.

"We have to solve the mystery of Why there were no "shooters" or almost 0 before the 1980's.I know one common denominator other than guns," Kirstie tweeted adding: "One additional common denominator of "shooters" is USA's mass usage of psychiatric drugs. A % do have side effects of VIOLENCE & SUICIDE."

Kirstie's personal view was met with some backlash from followers, with many labelling her as insensitive given the death toll of the mass shooting.

When questioned why she decided to tweet her opinion given the circumstance, Kirstie stood her ground replying: "It happens to be a common denominator in shooters..one that didn't exist before the 80's.. not my opinion. Statistic based."
