Would this work here, in a busy SA street?

The UK is adding loud speakers to its public camera system to allow the watching controllers to tell people to stop misbehaving. I think the first few times would scare the person into stopping, but what if they don’t understand English? Or what if the person breaking the law ignores it, send out the flying squad?

This 500 000 UK pound project will see many more cameras with speaker attachments in the UK, lets hope it’s money well spent.
