The teacher is not critically “ill”. She has been critically injured by a little thug. Maybe students should be required to fill out a form which asks if they are a child of gang members. This would give teachers a heads up as to the possibility of being shot by such a “child”.
I read one commenter say “I’ll withhold judgment until I find out whether she was grooming him or not.” Hm.
Maybe she was trying to misgender him, and he was offended. Was she using the correct pronouns?
