Well done Boris!

I heard today that London's Mayor Boris Johnson intervened to stop a gang of teenage hoodies attacking a women with a metal bar last night.

I thought fair play to him for stepping in and having a go. As the figurehead for London it shows good leadership and sets an example to the rest of us that maybe we shouldn't always be afraid to step in and help others when they're being attacked or abused.

It made me laugh when I heard he'd chased after the attackers calling them 'oiks' How very Boris! But maybe he was lucky to be intervening in the right place at the right time?

What if it wasn't a couple of teenage girls but a gang of older lads? The story might have been very different. I always think that this is a dilemma that we face.

Sometimes in our hearts we'd all like to think that we'd help out and do the right thing by helping others, but then your head takes the more pragmatic approach and you realise you could just as likely to be on the receiving end of violence if you try and do something. Is it really worth it?

The sad thing is if we all take the pragmatic approach and do nothing, we're just sending out the wrong message. People can act as violently as they like in public and people will turn away and do nothing.
