I’d agree with that to a point. However the answer isn’t to lock everyone up and shooting someone solely because they are suicidal is not right.
She wasn’t shot because she was suicidal (paranoid schizphrenics are rarely suicidal), she was shot because she was advancing on an officer with a knife, making herself a threat to him and the other officers.
This is what happens when law enforcement intersects with the violently mentally ill population, somebody dies. This time it was the mentally ill person.
The problem is that the dangerously mentally ill cannot be locked up until after they have assaulted or killed someone.
Liberalism kills in many ways.
