When you purchase a cd including a cd-rom, you will usually find that the retailer will refuse to give a refund, if the seal or wrapper as been broken. This is to stop people copying the original, and requesting a later refund, unless of course, it turns out to be faulty.
Copying your own legally purchased original cd, is okay as a back-up, for your use only. But if you sell the original, then you have no claim to have or use the copy.You have given your rights of possession to the new owner.
I would not think, that you will have your door kicked in, in the early hours of the morning,by a person with a legal warrant.Unless of course you have a 'mass production'facility going.
