More than half of all prison and jail inmates have a mental health issue. You can imagine the kind of reaction someone like me might have when delusions trigger an incident in which a police officer wants to engage with me or, worse, arrest me.
Three of my six arrests went relatively well, with police getting me into custody safely. The other three were extremely violent, because, in my head, I was fighting for my life.
