Well in a sense the security at events in Vancouver were supposed to enforce that. They did, with a thankfully human touch (you could persuade them to let you bring in things like chocolate bars, etc., but nothing overt like a bottle of Dr. Pepper). At most (non-sporting) events in Vancouver, you didn't even get a pat down. Dump your change in a bin, go through a metal detector, get your stuff and leave. Anything non-ferrous in your pockets went unnoticed. I somehow doubt the UK will be similar.
