Debating Going to Police about Stab Threats

On top of bragging about the rape from that apartment, I have been threatened to be stabbed on 3 separate occasions from them. Including "All it takes its one stab and you'll be in a pool of your own blood". But any-time I go to police. I'M THE ONE WHO GETS PERSECUTED AND ARRESTED, thanks to the local PD for nearly killing me and helping so many times on top of this!
