G20 security officials took responsibility Friday afternoon for a video that seemed to depict US troops ‘kidnapping’ a protester.

The military was not involved in the incident, but G20 security did acknowledge that “law enforcement officers from a multi-agency tactical response team” had detained a protester they said was believed to be vandalizing a store.

PITTSBURGH, the United States, Sept. 24 (Xinhua) -- Traffic slowed down in downtown Pittsburgh, Penn., Thursday morning as the city began fully unfolding a comprehensive security plan for the Group of 20 (G20) summit which will begin in the evening.

In the surroundings of the futuristic David L. Lawrence Convention Center, the venue of the meeting, concrete barriers were erected and several roads were closed.

National Guard members, policemen and other law enforcement personnel are patrolling on every corner of the downtown area that includes the convention center.

"I have to confess that the traffic restrictions will be sort of disturbing to us, but it's a great honor for us to host such a huge international event," Jacob Bacharach, who works at the Benedum Center theater several blocks from the convention center, told Xinhua.

Protests at the G20 economic summit turned violent at times Thursday with demonstrators throwing rocks and police firing rubber bullets, Pittsburgh police said.

Prohibition of any public disclosure of the names of alleged terrorists including those who have been arrested.

Automatic denial of bail for persons accused of terrorism-related crimes, reversing the ordinary common law burden of proof principle. Persons charged with terrorists would be required to demonstrate why they should be released on bail rather than the government being required to demonstrate why they should be held.
