The Safety Rangers are pretty useless...tbh
I get their whole job is being a crossing guard, but safety rangers are often absent when younger kids are being bullied, despite their motto being "safety". Usually when we do see them on screen, they're following orders and enforcing unnecessary rules such as in the Economics of Recess Episode. Let's also not forget that although we don't see them in the Pharoah Bob episode, we can infer they were working alongside the guards. 6th graders are already in the position of authority since their the oldest on the playground , so their inaction to the bullying could be seen as condoning it. I know, weird rant, but what do you think?
