I think for me - be it mass shootings, nut jobs with gas, dudes in cars etc. I've never believed that society or the government owes me a life completely devoid of all risk. The price I pay to be able to do the things I like is to assume some risk for myself and I should also be able to mitigate risk as I need to/see fit as well (CCW for instance).
I don't know when we decided that everyone is to be protected at all times - physically or their feelings but it's to our detriment. From a purely darwin or science perspective - the fact we continue to protect people who do dumb things - that is, they don't end up with consequences of being stupid and then they propagate - makes wonder if we're de-evolving by not weeding out actors that aren't the best and brightest.
I'm not calling for pograms - I'm saying, remove the caution labels and safety nets and let the chips fall where they may.
