The owner of says it will not have any extra security measures in place this weekend after a 24-year-old gunman opened fire in a crowded movie theater near Denver, killing 12 people and injuring dozens more.
Mike Mihalich said his employees will be more dilligent and aware, however.
"I've been in this business for 45 years and this is the first time this has ever happened in this industry," Mihalich said. "It doesn't appear that this guy is tied to any terrorist groups so it doesn't appear that this is going to happen across the country. We're diligent, we're going to be aware of it and check our exit doors more frequently, but as far as ramping up security, I dont have any plans to do that this weekend."
According to officials and media reports, the Denver suspect walked into the movie theater through a back exit door that was propped open with a rifle and several other guns. He is being initially identified as James Holmes, from the Denver suburb of Aurora, according to the Today Show.
Michigan private establishments—such as movie theaters, day care centers, churches, and other businesses—can prohibit you from carrying a pistol. If it is not specifically prohibited by the establishement, open carrying is allowed if the seating capacity is under 2,500.
A Denver police spokesman this morning told Matt Lauer that 10 people died inside the theater and two more died at a local hospital. The spokesman also said the condition of those injured ranges from minor to serious. He said "early indications" are that the gunman acted alone.
Holmes is suspected of entering a movie theater in Aurora dressed all in black, carrying a rifle and handgun and wearing a bullet proof vest and gas mask around 12:30 a.m., where the new Batman film "The Dark Knight Rises," was being screened, and opening fire, the Huffington Post reports.
In the third installment of the Batman trilogy, a villan named Bane wears a bullet-proof vest and gas mask.
Mihalich said MJR would be reviewing whether or not it would allow patrons to come dressed in costume as well as if it would continue to offer midnight screenings of new movie releases.
"I think the costume thing is something we will very well ban, but it's something we're talking about internally now," he said. "But look, if this guy would have walked in dressed as GI Joe and walked into the lobby at a 10 a.m. or 4 p.m. show, he would certinally draw attention and he would certainly be stopped and questioned by staff. At midnight, when the building is full - we had buildings last night with 3,000 people and many of them were dressed in costume - it would be much easier for him to fit in with that crowd unnoticed."
The Huffington Post reported that Warner Brothers had canceled its 'Dark Knight' Paris premeire because of the violence in Colorado.
Mihalich said while he doesn't expect a drop in ticket sales this weekend, he wouldn't be surprised if some people chose to stay home from the movies.
"This is a different kind of audience and hardcore Batman fans will come out and see it," he said.
Mihalich said he's very sensitive about the fact the shooting happened in a theater.
"I've contacted everybody this morning and said, look, this guy apparently got in through an exit door he had propped open earlier," he said. "We do periodically go around the building and check the exit doors, but we're going to do that more frequently. We also have extensive camera systems in all of our buildings. I'm a hands-on owner and I'm very concerned about the welfare and safety of my employees and my patrons. Anything I have to do to ensure that, I'll do."
