No charges were filed against the officers. The police are investigating themselves. I predict they’ll find that they did nothing wrong.
Edit: There’s bodycam footage. Don’t watch it unless you’re prepared to deal with extreme anger towards those disgusting pigs. I don’t think I’ve ever felt this angry and enraged in my life.
The US is the only country on Earth where you can get critically injured in a mass shooting and yet still be held personally responsible for the outrageous hospital bill.
