There is still a lot of conflicting information coming out of this, the official police story and timeline seems to be completely made up.
The MSM seems to have given up on promoting the story though after it became clear the perp was trans-adjacent (black eyeliner, cutting, bullied for posting feminine instagrams), cops did nothing, a border patrol agent, not police, killed the perp and that parents were being held back by police.
This seems a lot like Parkland, mysterious instructions to police, doors to the school left unlocked, armed guard missing from their post, police refusing to get in, an 18 year old living on a single parent income making minimum wage with a history of mental illness and repeated contact with authorities, drug and school problems getting their hands on $5000 rifles, an illegal hand gun, and a $45,000 truck, thousands more in optics, gear and bullets. The next 12 hours you have washed up politicians like Beto that have staged an entire scene with multiple people to make a public statement all in time for the midterms.
Like Parkland and Sandy Hook, a lot of these things don’t add up. I’m sure all these parents will come out of the woodwork to prescribe all forms of left wing ideals to solve the situation from gun control to universal healthcare and gender surgery. But solving the problem like adding security to schools and making school and police administrators (politicians) responsible for failing to act, oh no, kids may hurt their feelings seeing a gun or a locked door, plus then we’d have less problems we can use to prescribe our political priors.
