This cartoon is about profiling. A profile consists of a particular set of characteristics and behaviors that are deemed as suspicious by law enforcement. Profiles can be created by people or generated by algorithms that identify suspicious things from data of known criminals or terrorists.
At my event, the Privacy Law Salon, we have a wonderful tradition of showing some of the year’s funniest privacy videos after dinner. I thought I’d share some of the videos I have enjoyed the most, plus some new ones I recently found. Cookies In Every time you try and go on a website, British […]
This cartoon focuses on video recording – how people readily whip out their phones to record events involving people in distress.

One of the biggest differences between U.S. and EU privacy law is that in the U.S., organizations can collect and use personal data in nearly any way they choose as long as they state what they are doing in their privacy notice […]
