The good security guys don't work a hospital security job. As with everything else, you get what you pay for. The calm, humble, balanced types go for greener pastures.
NPR did a piece on this case last night. They emphasized that there are standard procedures for dealing with mentally unstable patients in a hospital setting, and the cops weren't trained in those procedures. They ended up escalating the situation.
They also interviewed a hospital security guard, who said the shooting was ridiculous. He said "We don't carry guns. We get hit all the time. We just deal with it."
That wasn't the police approach. One got hit, so they responded like they would on the street and deployed tasers, then lethal force, and followed up with felony charges.
Another issue was that the family asked for a mental health evaluation of the patient. Standard procedure is to immediately provide that upon request. Instead the hospital ignored it. Had they done a proper evaluation, the patient would have been moved to an area where they used regular security instead of police.
As of now the hospital is at risk of losing federal funding, if it doesn't reform its policies to the satisfaction of federal investigators, including better training for the cops and further restriction of their areas of operation.
It's stupid that we now have this idea of competing hospitals. It's a competition to the most efficient lowest common denominator cost wise yet maximalized cash cow.
Seriously. Stay healthy. Stay away from doctors. Stay away from hospitals. (Family full of doctors who always say this.)
