but what if there are two or three at every entrance
one dies but the kid gets shot by the other one
but what if the whole school is full of secret government ages disguised as kids, and the kid with the gun was just a social experiment????
In all seriousness, cops/security guards/whatever are instructed to shoot to kill, but they are also instructed to intentionally shoot to maim and disarm, which the latter would occur in this case.
With good planning, you could do tons lol. For one you could make a bomb (which actually isn't that hard) and place it hidden right at the security entrance, then run in and shoot the armed opponents, from there you'd be fine until the other guards show up at the blast, by which point you'd be far away.
