I Kill You!!!!

Since I work in a big hospital, there are occasions when the patients we care for are prisoners from the surrounding areas.  Many times, people are scared to enter their rooms because they are afraid they will get hurt, however, I always think these are the safest patients because there are always at least one guard stationed in the room.  The patients that always make me a little paranoid are the patients who have a mental health issue.  There are no guards in their room, and many times, it is impossible to tell what they are thinking or about to do. 
One patient in particular this week has managed to make most of the staff members wish we did not have to enter his room at all.  He was admitted for osteomylitis in his spine secondary to a past gunshot wound.  From the minute he was admitted he was telling stories of his time in prison.  While making conversation he would expand that it was because he had killed his first man when he was 10 years old.  As he continued to talk his stories became more and more violent and graphic, until he reached the point he was threatening every person who entered into his room. 
Well of course I was the lucky person who got sent into draw some labs.  While I was doing this, he was screaming at me and threatening to throw me through the window.  It was quite fun.  Honestly, I got the impression he threatened everyone but would never really act on his threats.  He said he was going to bring a gun in and shoot everyone, he threatened to kill his doctors because they didn't know what they were doing, he threatened to kill the cleaning ladies because his room was never clean enough.  In fact I didn't really pay attention to most of the the threats.  However, that changed really fast. 
When I returned the next day, I was met with serious faces.  The day nurses informed me that the patient had physically threatened one of the staff members and was now a candidate for having a security officer stationed in the room with him.  However the patient could still go down to smoke unsupervised because of course we do not want to invade on his privacy (really! Honestly...how does this make any sense!!!!????).  During one of these trips down to smoke, we received a call from another security officer informing us that they were going to return the patient to us, and he was no longer allowed to leave the floor. Apparently this patient had physically grabbed a doctor in the hallway and was beating him when the officers showed up.  The reason "I don't like those foreign doctors."
