You should have been thinking this for a while already, US border crossings have been getting steadily worse. Every visit to the US I first replace the harddrive on any laptop I bring. I also image my phone (rooted Android) and reset it, installing a minimum of apps and data, with no important accounts. Once across and on a decent network I retrieve whatever data I need. This doesn't protect against evil maids or other advanced attacks, but I figure it's good enough for power hungry border crossing officials.
