Police in cities across America are ramping up police presence around theaters showing ‘Joker,” which opens nationwide on Friday.

Los Angeles police have promised a “high visibility” presence around cinemas “to ease fears that the latest big screen comic book adaptation will ignite deadly violence,” The Times of London wrote.

New York City plans to do the same.

“As part of the continuing hysteria surrounding Joaquin Phoenix’s Joker film, New York City police will now patrol outside theaters screening it. In an age where mass shootings have become commonplace in the U.S., it isn’t hard to understand why concerns about such violence exist,” ScreenRant.com reported.

TMZ reported. Law enforcement sources tell TMZ … the NYPD doesn’t want a copycat crime of what went down in Aurora, Colorado 7 years ago and is taking a “precautionary measure” by dispatching uniformed police officers to every theater across NYC screening the film. “Moviegoers in NYC will notice a hefty police presence when they go see “Joker” on opening weekend … cause the NYPD’s not taking any chances on someone acting out,”reported.

We’re told officers will be patrolling in front of theater entrances, though the public should be aware police have not received any specific “credible threats” to the Todd Phillips film starring Joaquin Phoenix as the Joker.
