4th Amendment, unreasonable search. And of course the 2nd, but the former is more worrying. Also if printing is speech, then you can add the 1st to the list as well.

The 4th amendment has probably been the most eroded of all the major private liberty amendments, in my opinion. It is, at this point, a pretty worn fig leaf.

The problem is, nobody is willing to use 2nd amendment rights to defend other amendments.

Right, so they can't use the blocked print as cause to get other evidence. Or if they do it is excluded.
