Austin Lyle is an example of a liberal failure when it comes to violent behavior.
His previous violent actions and possession of a weapon was known by the school. In response to his prior disregard for laws and rules they created a safety plan with new rules (pat down to enter school, by an unarmed school administrator). The answer to not following rules is to create more rules which of course he did not follow. Now two school administrators are wounded and he is dead. Of course the plan now is to put police officers back in the school, they were removed to appease the woke anti police crowd. Maybe actually prosecuting him and educating him while incarcerated would have had a better result.
