[hypothetically speaking]ok lets say my friend obtained one of hi former teachers credit card info.

now lets say my friend, wanted to make some purchases on-line, with thus info. how easily can that shit be traced back to him. should he use a library computer to set up a pay-pal/ ebay account. or buy stuff online through the library. basically he wants to know how easiily he can be traced and caught.[/hypothetically speaking]
