SAN FRANCISCO – The British government has unveiled a tool that it says can block extremist content on the internet with reasonable accuracy.
It does seem that those who commit terrorist murders on our streets are increasingly influenced by what they read and what they see online.

The new software, developed by London-based ASI Data Science firm on behalf of the British government, can identify and block 94 percent of propaganda video of the Islamic State group with 99.99 accuracy, British Home Secretary Amber Rudd said on Tuesday.
Rudd is on a two-day visit to San Francisco meeting with tech giants and US officials to discuss how to better combat extremists on internet platforms.
Rudd said the software is designed to be offered to small tech firms that cannot afford to develop such systems. She did not rule out forcing technology companies to use it by law.
"We're not going to rule out taking legislative action if we need to do it," she said.
The secretary said that last year, all of the five attacks on British soil had an online component.
"It does seem that those who commit terrorist murders on our streets are increasingly influenced by what they read and what they see online," Rudd said.
Last year, IS supporters in Britain used more than 400 separate online platforms for propaganda, according to British Home Office analysis.
