They should not have reported, I guess. That’s just wrong. Two intelligent, well spoken, sincere college students fend off an intruder and some liberal idealogues are going to ruin their college careers (maybe lives) over it. Having an expulsion on their record will make it difficult for them to transfer to another university of any prestige.
I would sue the university for enough money that they don’t need a college education. At a minimum I would sue for the entire value of their education and lost educational opportunity at the university.
They did the right thing by reporting, to not report could have led to a problem from some other unsuspecting student. Liberals create gun-free danger zones and when their “security” fails to “secure” and a citizen does the citizen must be punished in some way. The university created the problem they need to fix it.
