EFF's Fight to End Warrantless Device Searches at the Border
From the linked description of the plaintiff's accounts, a US citizen:<p>> <i>.. A few days later, while returning from a day trip to Canada, I was once again detained and told to hand over my phone. When I refused, three agents used force against me. One agent grabbed my neck and began to choke me while another wrapped up my arms and legs. The third agent reached into my pants’ pocket and took my phone, all while I was in severe pain and fearing for my life.<p>Agents once more took my phone out of my sight, only to later return it without any explanation for what they did with my phone.</i><p>I had not heard this account before, and it's pretty shocking. I had assumed that while migrants/permanent-residents could be denied entry, US citizens could have their time-wasted/device-confiscated at worst.<p>I didn't realize that the government had given itself the power to literally beat physical access to personal computing devices out of people without a warrant.
