I think this is the right place to ask this.. If there is a young child (say 4-10-ish) who is unsupervised and causing a major disruption, what is the extent of the measures you can take to stop him/her, as far as the law is concerned? When I say causing a disruption, I mean things like trashing a store, or spitting on passerby, or being aggressive, or even less important rules, like cheating at an arcade game, such as skeeball? I'm wondering basically because I watched this video: https://www.youtube.com/watch?v=NuHLsPVeqLU As a normal person, watching, are you alllowed to intervene? Do you just have to deal with it, or can you forcefully make the child stop? I want to know from a legal standpoint, rather than moral.
