  • There’s a Cop in My Pocket: Policymakers Need to Stop Advocating Surveillance by Default

    All this year, U.S. leaders have attempted to pass a wave of misguided online security bills, designed to break that encryption and place Americans in a panopticon of surveillance by default. Encryption, cybersecurity, and technology policies, like the RESTRICT and EARN-IT Acts, with nonexistent tradeoffs address symptoms, not problems, and they do it badly.  

  • Prosecuting Extremists in the U.K.: Charging, Prosecution, and Sentencing Outcomes

    There is a lack of data regarding prosecution and sentencing for terrorism and terrorism-related offences across the three legal jurisdictions of the UK (England and Wales, Scotland, and Northern Ireland).

Analysts say Washington and its allies are showcasing an “inter-alliance cohesion” through these coordinated activities.

  • The Vital Role of the Civilian Community in Responding to Natural Disasters

    Disaster preparedness is not about prediction. Leaders shouldn’t get caught up in trying to define what precisely we need to prepare for and when. Instead, they need to be ready for compounding national disruptions of any kind, at any time. Given the interconnectedness of our modern world, integrating broad economic, social and environmental preparedness will be better for resilience than mapping out overly detailed contingencies.

  • Wildfires Are Much Worse Than a Sign of Climate Change

    Summer headlines have screamed of climate extremes: Record temperatures, an ocean heat wave, and rampant wildfires. The fires present a dual problem: Not only are they a symptom of climate change — becoming bigger, hotter, and more common in regions where they can affect large population centers — but they also make the crisis worse. By burning vast layers of partially decomposed vegetable matter called peat, fires like those in Canada release even more greenhouse gases into the atmosphere.
