I was crossing into Canada and 3 agents demanded my phone and password (as well as my SO) under threat of detention. They took the phones in the back for 45 minutes before they came out. Asked questions about a conversation I had about marijuana with a friend months ago, basically accusing me of being a drug dealer when even in the most wild reading of that conversation, that cannot possibly be the case. Anyway, who knows what happened in that 45 minutes, probably our data is still sitting deep in some Canadian government server somewhere.
