Too many people with mental problems on the streets, attacking innocent bystanders. This person was one of them according to eye witness accounts. Did the defender go to far defending them? Definitely. But let a jury of his peers decide.
I see crazy people everywhere. I call them "street performers". They are crazy people just standing in an intersection jumping up and down waving and screaming at passerbys, making faces, doing dances, jumping in front of traffic ...anything for attention.
When they get no attention they get violent. Hopefully the police are there to take them to county hospitals for mental treatment.
My brother went to a county hospital not too long ago for a broken ankle. It was filled with crazy people. Lots of them who did not want to be discharged, most were on mental drugs like Prozac, etc.
My brother said lots of people had to be ejected by hospital cops because they refused to leave. Others had to be tied up in beds and given their mental drugs.
Total craziness these days.
This is not an isolated incident. Sometimes these crazies get guns and go on killing sprees. I blame over population. It is sad but true and there is not much we can do about it.
