Interesting and insightful documentary which sadly is derailed at times by a left wing bias particularly noted in episodes 3 and 5. An appropriate examination of this topic must find a fair middle ground between civil liberties and security, and this work is clearly slanted to the former. Many of the observations in episode 5 are particularly ironic given the results of the recent total withdrawal in summer 2021. Overall, the documentary was worth watching in spite of it's shortcomings
