In the second, it's hard to know if the SRO overreacted - we weren't there. It doesn't sound to me like he did. Without more evidence, you have to trust people in authority to carry out their jobs.
IOW, if they're given pepper spray and a Taser, then one has to assume they are given proper training and discretion on when to use it and when to threaten to use it.
Again, I don't see the problem.
Children must learn to obey the rules and do as instructed. If there's a problem with the rules and the instructions, well that's something for adults to address.
My $0.02.
Cheers,
