That may allow protestors to be seen and heard by delegates going in and out of the Pepsi Center during the convention.

But the American Civil Liberties Union and several advocacy groups have filed an amended complaint to their lawsuit against the U.S. Secret Service and the city and county of Denver that says protestors and demonstrators may have their First Amendment rights violated by security restrictions.

The ACLU has said it wants to avoid the conditions that existed during the 2004 convention in Boston, where protesters were caged, infuriating First Amendment advocates.

During today's hearing before Judge Marcia S. Krieger, the attorney for the groups, Steve Zansberg, said the city and the Secret Service had provided the information sought in Phase One.

The second phase of the lawsuit will address whether the restrictions are unconstitutional. Zansberg also represents The Denver Post on First Amendment issues, though the paper is not a party in this dispute.

The groups agreed to go to trial on those issues on July 29 and the judge will visit the site the night before to assess the restrictions.
