Animal Aid, incidentally, have just released a ludicrous video of their "Undercover Footage From The 2008 Gamebird Shooting Season" - several minutes of wobbly video of, gasp, people firing guns in the air. Gosh, never knew that happened on shoots. And, ooh, a gundog retrieving a shot bird which is promptly dispatched by the handler. All interspersed with some even wobblier shots of a sick partridge in a pen. As if that proved anything. Oh, and guys, if you walk up to a larsen trap and poke a video camera at the decoy bird, you are causing it distress. Please don't.
Honestly, if people want to see what happens on a shoot, there's no need to skulk about in the bushes with a handheld camcorder. They only have to ask. We have nothing to hide. Unlike certain animal rights activists.
