United Kingdom

The United Kingdom has put in place several strategies and laws to prevent the misuse of the internet by terrorists. Most notably, the Terrorism Act 2000, in conjunction with the Terrorism Act 2006, serves as a guideline to all legal actions and strategies on this specific matter. In 2019, the UK Parliament passed the Counter-Terrorism and Border Security Act, which outlaws the viewing and downloading of terrorist content online. Additionally, the Counter-Terrorism Act 2015, which refers to the Data Retention and Investigatory Powers Act 2016 (the original 2014 DRIPA Act having been repealed) provides a legal context for governmental prevention of the use of the internet for terrorist purposes. The CONTEST program, which is the UK’s general counter-terrorism strategy run by the Office for Security and Counterterrorism, aims to “reduce the risk to the UK and its citizens overseas from terrorism”. The UK National Cyber Security Strategy, on the other hand, is a five-year government plan aimed specifically at strengthening the security of the UK’s use of cyberspace. The Strategy is based on three pillars: Defense, Deterrence and Development. The British government acknowledges in the Strategy the rise of a computer-literate generation engaging in extremism online, and challenging legacy counter-terrorism regulations.

The law criminalizes the “downloading” of the material, except when (a)  “at the time of the person’s action or possession the person did not know, and had no reason to believe, that the document or record in question contained, or was likely to contain, information of a kind likely to be useful to a person committing or preparing an act of terrorism, or” (b) “the person’s action or possession was for the purposes of (i) carrying out work as a journalist, or (ii) academic research.”
