In Denver? Make no sudden movements

DENVER -- As Denver braces for tomorrow's start of the Democratic National Convention, a multi-block perimeter around the convention site is under a heavy blanket of security. Heavily armed police are on foot, on bikes, in armored trucks, in unmarked cruisers, and even driving a pimped-out golf cart borrowed from the Los Angeles police.

Jersey barriers and metal gates are everywhere. Major streets are closed. Helicopters buzz constantly overhead. Major stations in the city's light-rail system are scheduled to be closed from tonight through the end of the convention.

As of mid-afternoon, police had reported few problems and no major arrests. One Denver police officer said there were reports that self-described anarchists are intent on causing trouble, perhaps even planning to physically prevent delegates from entering the hall. Anti-convention activists have loosely organized events planned all week.

The heavy security has placed limits on the media -- as of today, there is just one way in and out of the convention site for the 15,000 representatives of the press expected to be here. At times yesterday and today, it has taken well over an hour to get in.
