Hi, welcome to PC and yes please be careful with your choice of words on here. You could easily offend people by making generalizations. Not all are dangerous. I hear voices myself and am on medication for them. I am not diagnosed as schizophrenic and I do not have any other symptoms that indicate I am, but I hear voices and am probably somewhere in the neighborhood. I am not dangerous.

This man does sound a bit out of control, though. You may need some outside help.
