Demilitarize the police!
Then demilitarize Hollywood!
Do both at the same time. Hollywood is easy. Just pass a law (because leftists in Hollywood love laws) that makes it illegal to display any weapon that an average citizen cannot buy in less than an hour in a sporting goods store in the city where the movie is set ( if it’s set in a foreign or fictional country, then use the gun laws of Washington DC). If the story requires a weapon that people can’t buy, then require the producers to use a bright red fake gun and use a sound effect of people saying “pew pew pew”. Suddenly, Micheal Moore and the rest of them would discover the sanctity of the Second Amendment.
And NO explosions because that could trigger someone in the audience.
