One big difference is that one was done by an adult. Now we are faced with a whole bunch of kids who are fucked in the head with far more advanced weaponry compared to 1927. Yet the adults keep ignoring the kids and despite all previous warnings, continue to let it happen. If your child was already previously being investigated for threatening to shoot up a school, then you damn well better help them. Sell your guns and use the money to get them some therapy. If you get calls saying there are going to be shootings, you don’t sit there with your thumb up your ass until a bunch of people get massacred, yet that is exactly what happened.
The indifference, apathy, media sensationalism, and bullshit thoughts and prayers just make it worse. As soon as the media stops talking about it, it may as well never happened. Maybe some sob piece months later from the parents, but those are barely a footnote. Our country is fucked. Darkest timeline.
