Other experts warned that despite the social media companies claiming they can identify and remove extremist content within hours of it being posted, they are still not moving fast enough. According to the non-profit Counter Extremism Projects, Google has yet to take down a bomb-making manual that was used in a thwarted terror attack in the U.K. As of Tuesday, the YouTube page of extremist Abu Haleema was still accessible. Haleema has suspected ties to one of the terrorists in the June 2017 London Bridge attack and was previously arrested for attempting to travel to Syria to join an extremist group, the Counter Extremism Project reported.
