Do you think getting the operators arrested can solve the issue?
I have read alot of members advising that she should arrest the operator and that is not a good advise.
Lol, citizen arrest is somehow risky, besides I would not advise that move since she can endanger herself in doing that. It is best to let the authority do the arrest and just provice a solid evidence regarding the illegal activity.
Doing that will be her bringing more problems for herself with the operator who obviously will have more money than her, and with people around that place who will begin to see her as a bad girl.
True, it will cost the girl more problems because she initiates conflict against the illegal gambling operators which can put her life at risk. But I do not think the action will make the girl the bad guy.
My advise will be a bit harsh but that is what will solve the problem. She should set the brother up so that his brain can be formated. Formating the young gambler's brain is what will do it. Let her arrange with a soldier who will walk into the gambling shop when she is sure the brother will be there. But she has to pretend not knowing the soldier. Just make it look like a coincidence. And the soldiers knows what to do when he sees an underage gambler. By the time he frog jumps him or takes him to the barracks for proper discipline, the next time her brother hears of gambling he will run far off.
The problem is authorities can't detain kids that are involved in gambling. Instead of catching kids, the authority should capture the operator first because the operator is the root of the problem. These entrapment is a good idea but the way you wanted it to proceeds is impossible to happen.
