My issue here is I would have gotten my kid. Lockdown or not, he/she is safer with me than with any school official. Period. I always carry.
Not letting your child out is equivalent to false imprisonment. There is no statute that says they can keep your kid if you want him/her. School is once again overstepping them bounds once the suspect left ther property. Fear of his return or not parents wanting their children get them.
So, if they deny you, do ya shoot your way in to get your kid?
You might be going a bit overboard with the false imprisonment thing.
