Sure, but in this case, the man's ability level doesn't even seem relevant.
Officers see a nonviolent man taking a shower. No weapons seen by officers. No weapons reported in the 911 call. Man is naked, also suggesting nothing concealed. Man is acting unusually but does not appear to be harming himself and is not uttering any threats to officers.
Yet a team of armed and armoured law enforcement officers think they are at risk? They respond with electric shock, physical force, and injecting drugs!
The ability level of the man is irrelevant. These are thugs and I think their problem may be deeper than gaps in their training.
