Un cancelled stamps

[arnold cheshire]

Why at christmas do the Royal mail allow so many un cancelled stamps through the network. I see so many stamps being reused some don't even bother to hide the fact its reused and cut round the stamp and stick it the the envelope.
Surely the Royal mail should be protecting its exposure to fraudulent use of stamps. We do all this hard work to make sure all the post is delivered and then allow people to peel off the stamp and use it again, its crazy

this could be seen as defacing mail as zx bloke will tell you avoid
