I figure at some point, the local lefty crowd near incidents like this (especially in a large city like Miami) will shift gears a bit and insist that it's "only reasonable" to make a law that anyone who has a negative entry made by a trangender or otherwise clearly politically conscious teacher in their school k-12 records ever in their life be allowed to own a firearm. You know, all the negative indicators, like having a Bible in their backpack, defending a Republican or Independent candidate, parents who aren't at the right protests and meetings, being neat and clean rather than inclusively scruffy, etc.
At which time the threat frequently made by teachers back in the fifties, "An entry in your permanent school record follows you all your life" will become something other than hot air to intimidate the kiddies in second grade.
This kid was clearly troubled.
Shovel him off to the experts.
Kids need Discipline which the adults apparently did not have
