There's a petition at the Number Ten website, asking for the law to be changed to allow citizens to carry concealed handguns in the UK:
The problem with banning weapons is that criminals don't obey laws, so when guns were banned criminals ignored the law and kept their weapons, and decent law abiding people were left defenceless, as is the case now. This is simply because guns, in the right hands, are a serious deterrent against acts of violence. An example of this is the US state of Vermont, which has virtually no laws against gun ownership, and a crime rate which is a fraction of that in Britain. The simple fact is that by disarming honest citizens, Britain has actually helped criminals, who now go about their business without fear.It's been signed by at least one elected representative, Councillor Gavin Webb. It has also, apparently, been signed by "tonyblair". And now it has been signed by me.
