Nice link E; A cursory reading; international or border crossing search is a no-brainer; it is like they say; if you can be searched at the border than communications are implied in that same doctrine. I am reading the case record but it is long. While that is onging allow me to present the arguments made for the same reasons back in 1970 and the Nixon administration. No terrorist organisations were even searched just anti-Nixon groups. Thats my complaint. Back to the case law.
