I got a friend who is mentally ill and is homeless sometimes, police beat him up and arrested him for being at a McDonald's on his Macbook. He was in jail for a year, gave him the wrong psyche meds, kept delaying his preliminary hearing until he had to plead guilty to get out of jail. Charged with threaten with intent to terrorize and only the police officer's word against his for evidence.
I am mentally ill myself, I became disabled in 2003. In the IT industry one has to keep the mental illness a secret or else they lose their job or end up not being hired for jobs. Basically my career was over when I developed a mental illness.
I can tell by Ian's tweets that he was not in his right mind. I hope his family files a lawsuit against the police, because they basically forced him into suicide for whatever they did.
