Hunters Rubbish

Saw this by the Lake, first, Hunters are supposed to take their spent cartridges with them, second, the whole area is a Nature Reserve, so wht the H--l was he doing shooting here, also the Car Park is less than 3o metres away, so must have been dangerous for passers by. Still he was quite likely drunk, most Hunters drink every time they shoot something, to celebrate their Great Victory.
I threw said Case in the rubbish bin which was only 15 yards away.
