LOL!
What utter foolishness.
Recently, I saw a BBC TV documentary calling for a certain make of airgun to be banned immediately, because some gangsters have found a way to adapt them to fire .22 calibre rounds. In the TV program they mentioned the case of a man who was killed with one of these adapted air-pistols last year in London. However, they didn't say it had been illegally adapted to fire real bullets, they just said he was killed with a lethal air pistol! The misinformation being put out by the media is amazing.
