from the article:
Hmm. Some troubled soul a) had a shitty life, and likely a mental illness; b) could get no help for one reason or another, all too common; c) was able to acquire a firearm; and d) made it happen in a town where the five-oh are placing their retirement above their sworn duty.
Do we need to get deeper than that? I see 4 very clear action items: a) better attention to mental health issues; b) unprejudiced support, and funding for the former; c) reasonable control of firearms; d) training for the police on things that matter... What's deeper?
