Our Constitutional rights were written without any concept of modern technology such as cell phones and the internet. Much of our privacy laws are still geared towards the pre-digital age. Even though the internet is many decades old now, the era of traveling with smartphones and laptops is still relatively new and the laws around privacy have not kept up. Today I’ll be speaking with Nathan Freed Wessler from the ACLU about device searches, particularly at the US border. We’ll also talk about how cases relating to location tracking have evolved since the landmark Carpenter case that Nate successfully argued in front of the Supreme Court almost 10 years ago now.
