On this subject an employment attorney told me that with the digital age upon us that all records are perminant. He says that there are several large data companies that collect everything they can especially criminal and financial records about everybody. If a government record is put out and it is public then they collect it and there is not law that says the must delete it. Law still appy to the companies that ask for it though but how are you going to know what they see. Now the government is a big client of these companies so you know they arent going anywhere.
Other companies like microsoft and google even keep track of IP addresses and the searches used from that computer and then match them up with names from email and credit card info.
Privacy is gone fellas.
