Almost by definition there is something wrong with the mental health of mass shooters like the Aurora cinema guy, the Sikh Temple shooter and the one who just killed 20 elementary school children, 6 staff members, his own mother and ultimately himself.
In parallel with the calls for better gun control in the US we experience calls for improved health care for the brain. But the failing is not the provision of care so much as it is the detection of mental health problems that might lead to mass shootings.
We will never get to a one to one prediction of who is about to become the next news cycle. But then, we don't know who will heal eventually from a given infection, who will recover from stroke without a given intervention...or who will get heart attack save for the cholesterol meds, statins and what not.
So we go with the odds.
And we detect problems with broad screening (annual checkups), acute responses (minor cardiac event perhaps)...and crowdsourcing.
If someone were bleeding in front of you, chances are decent that you would know whether to get a bandaid (even a 5 year old knows to add the antibiotic cream) or stick a finger on the vein while yelling for help. In a crowd? Someone would know CPR if a person stops breathing...in a pinch you'd have a go based only on what you remember from teevee shows.
What about when someone shows signs of a mental health problem? How does the crowd and pre-FirstResponse do with those situations?
I have only recently been made aware of Mental Health First Aid.
It intrigues me.
