Last time I went to Toronto, the Border Patrol wanted my old HP turned on so they could browse my files. I was pulled aside and had to plug in and wait for my battery to recharge. They got it all; pics of my kids,wife and cats, the PPs of the cabling layout, an unfinished tax return (unencrypted), and some spreadsheets. When they saw the PPs, I had to play them and when they saw the architectural drawings with "all those lines", the CMP wanted to know what those were (especially since it had an address on it). 3 hours later, I got to go. I think I empowered those that were downtrodden that day. Made them feel important instead of impotent (there's a joke in there somewhere). No Due Process, No Warrants, Just a simple command, "turn it on and let us see what you have" ... or else.
