It will lead to nothing, unless you (yes, you!) start complaining and mobilizing because of this. This won't likely cause mass change, and the Uvalde shooting will be written off as bad apples instead of symptomatic of a large problem that needs solving. What it can do is awaken individuals to the problem, and get them to work on solving it in their own communities/volunteer with relevant groups. I'd personally either your local libertarian party affiliate if you have time (the party that recognizes the endemic problem and then doesn't use it to race bait), or the Institute for Justice if you got money (think ACLU, but not woke, and also does economic justice like suing to stop stupid regulations).
The libertarian party can likely hook you up with a relevant group for your area that's more focused as well.
In addition, call your representatives. Both state and federal. There are ways to fix this locally by states reforming qualified immunity, but the right doesn't think to do them because they assume their voters are on the opposite side. Call them, change their minds.
