On Saturday, Kennedy Park will be crawling with police. And FBI agents. And a couple of bad guys in orange jail suits to complete the scene.

Take a breath, friend, none of it will be real. Those aren’t police officers, as it turns out, they’re actors. The snarling dude in the jumpsuit? Also an actor.

All the hubbub in the park will be the work of Alegria Mangala Kinfumu, a filmmaker from Angola who is working on his latest project, a film called “The Murderer.”
