Again, you are letting your prejudice lead you. A 16 year old strapping lad is just as able to be set upon by a group of thugs. You also don't know whether that 16 year old is able to navigate themselves home, maybe doesn't have parents who will come and pick them up.
No, they're not, they're much more in a position to defend themselves. I'm pretty big, nobody has ever gone for me. People have sense.
Either people on here are overstating risk or they live in a bizarre state of permanent fear!
Is it, though? Chucking someone off doesn't fix the problem, it pushes the problem to elsewhere.
It associates consequences directly with actions. It's very powerful. That's why I think we need to do much more of this kind of thing. For instance I would arrest anyone who steals from a shop, even if only tenpence worth, and give them a night in the cells. Release at noon the next day to make sure they have to explain why to their boss, too.
The sort of simple brain that doesn't think past the selfishness of these actions needs simple and immediate consequences. Way back when that was a clip around the ear. I don't support returning to physical violence, but I do think things that are analogous, e.g. a long walk home, are simple, effective and appropriate.
I do agree on this one, hopefully in that circumstance hopefully the teens then get the message and behave. However, what happens if the kids don't stop. Do they sit there all night? Does the bus driver want to, maybe it's their shift before clock off?
If they don't, then the bus is cancelled. Lights off, engine off, everyone off, refusal means the police are called. In my observation the success rate is near 100% - some big scary bloke always intervenes.
