not paranormal but i went to a felon factory highschool and a literal crackhead posted a picture of a hunting rifle on his social media and said he was going to shoot up the school while on a several day long drug binge. All that came of it was cops raided his fathers house, found a growop but no gun and left him with a warning. School gave him a lengthy suspension. That was it.
I mean he never ended up doing a school shooting but i think back on that a lot and realize now how so many of these shootings end up happening despite ample warning signs...cops exist to protect banks and insurance companies and the education system is filled with do nothing retards. There is nothing impeding these people, no real punishment, no system to stop them.
