I would not a call it extraordinary effort by cops.  Patience by cops should "ordinary" Hillside or anywhere. Impatience by law enforcement is killing too many citizens. around the US.  Anchorage cops actually show lots of patience on these situations and has a citizen I'm glad.  

Cops get injured. Its part of the job unfortunately and they know it. Lost of people do dangerous work everyday outside law enforcement to help society. Just because they wear a uniform doesn't mean they live on a pedestal.  It's tough work, but a lot of people do hard, brutal work that helps society be safer.

Sad to see this guy loosing it and hope they can rescue him from his illness and get him help.
