> some types of mail are protected by the 4th amendment
> The law doesn't see a difference
Wow the cognitive dissonance in that is painful to read. Your argument sounds like "Shrodingers cat". It is and isn't at the same time. Ultimately though, it has to collapse into one objective reality ;)
> If you send a document through UPS, there is no expectation of privacy.
Yeah, again, no. This is directly contradicted by supreme court cases like:
"No law of Congress can place in the hands of officials connected with the Postal Service any authority to invade the secrecy of letters and such sealed packages in the mail; and all regulations adopted as to mail matter of this kind must be in subordination to the great principle embodied in the fourth amendment of the Constitution."
But then again, some people view laws (like 39 U.S.C. 3623, supreme court precedents or other such concrete objective reality as impediments that must be overcome to see reality as they choose to see it.
> you should read the words package/letter/mail/correspondence interchangeably.
> some types of mail are protected
Aside from the obvious contradiction, that's not how language works. You should really look up these words in a dictionary. It will help you communicate better.

P.S. it is a scarecrow because you are answering someone talking about Letters with what happens to packages. This is textbook scarecrow arguments, where you change what is said to attack a new, different argument than the one provided.
