The gunssavelive link in the OP was certainly heavy on what at best can be said to be extreme wish fulfilment, and at worst outright lies. For example, it relies on a 2009 Daily Mail article screaming that the, "total number of firearm offences in England and Wales has increased from 5,209 in 1998/99 to 9,865 last year [2007/08] - a rise of 89 per cent." This was highly misleading, given that the peak years after 1998/99 were actually 2004/05 & 2005/06 at 11,069 & 11,088 respectively, after which there was a fall to 9,645 and then a slight rise to 9,865. There were then fall for the next three to 7,024 - obviously this is after the DM report, but these figure are publicly available, so either gunssavelive knew about them and therefore misrepresented the situation , or were too stupid to find them. And even so, the devil is in the detail. In 1998/99 11% (n=566) of offences were known to be imitations, but by 2007/08 it was 26% (n=2,562), and had been around 30% in the two peak years (n=3373 & 3277). These were, of course, the crimes positively identified as involving imitations - the vast majority being Airsoft types - and the real numbers are likely to be much higher.
The Telegraph poll, of course, is beyond a joke.
