In my opinion the effects would be similar to those punishments handed out in Singapore and Malaysia.
My wife and I have visited Singapore frequently on our way to from different parts of the world. We always take the opportunity to stop over for a few days there and marvel at how safe the streets and shopping malls and parks are. The Singapore government has very strong measures in place as most of you are aware, against violence, vandalism and drugs. In my opinion they are to be admired for taking a stand against the increasing violence of the world that surrounds them. You can walk around Singapore safely, without fear as long as you observe the local laws.
