Aside from the fact that there were many false flag posts about this "shooting", as others pointed out, I just don't think it warrants as much attention, in terms of false flag analysis. It wasn't so unrealistic and ridiculous, as some others. Compare this to a scenario where there is no video or physical evidence of any kind that the public gets to see, but we are expected to believe that 26 children were massacred, with a 100% shot:fatality rate, by a scrawny nerd with no training (whose brother happens to look exactly like him), or that some gamblers guy got angry because he wasn't getting proper VIP treatment at his casino, so he went upstairs to his suite and used, for some reason, 8 different copies of basically the same gun, which he brought with him from another state, just to shoot down into a concert taking place below, or that some Muslim ran into a homo nightclub and killed like 50 people in minutes, or that some psychotic teenager went into his high school with a gun and killed a bunch of people, meanwhile multiple witnesses say that they saw people with helmets and body armor carrying guns during the shooting, and at least two witnesses say they were talking with the supposed shooter while walking downstairs with him while the shooting was still going on, etc., and multiple students stated that they witnessed what appeared to be bodies being dragged out of a room into the hallway during the shooting, by guys wearing helmets.

Most of these big "shootings" just have so much about them that is automatically suspect that it's impossible not to dig into them deeper. This situation is pretty basic, by comparison; somebody supposedly goes into a school and kills just a few people and then is killed. Not to mention, the only thing really suspicious that I've seen so far is the shoes, and, as I mentioned in the post that I made about them, while there is some weird digital anomaly going on, the shoes in the hallway footage are definitely not the puma shoes that others have been claiming. Assuming there is a reasonable explanation for the digital anomalies, and assuming there is some valid explanation for why the alarm system was apparently going off immediately upon her entering of the school (this one seems obvious, somebody in the office heard the gunshots and put the alarm), then it's quite possible that this was just an actual shooting. The numbers are realistic (you can't just go into a lockdown place and slaughter hundreds of people instantly).
