Why was the 4th Amendment created if we were not to have personal privacy?
Privacy means that you are immune to ID? I do not buy that for a minute.
Does that mean any use of your ID is ok? No I do not offer such an idea. You ,like others, are mixing the ID itself with its uses/abuses.
Protecting your ID from abuse is a good thing. Are you claiming this cannot be done except by eliminating ID alltogether? Sure sounds that way if you think the fourth (or any other) was adopted to keep ID totally secret.
