Los Angeles Police Chief William Bratton on Wednesday pledged to conduct an internal investigation to determine if police violated policy by using force to quell pro-immigration protesters.

Bratton said he had seen news footage showing a number of officers in riot gear striking protesters and some members of the media to the ground with batons, and others firing foam bullets into the crowd.

The incidents happened during a Tuesday rally in downtown Los Angeles.

"I regret and am, as are all of you, disturbed by the events so vividly depicted in the various news videos," Bratton told a press conference at the city hall.

"Police use of force in any context is always visibly and emotionally upsetting, even when necessary and lawful," the chief said.

"Our challenge in reviewing and investigating the actions of the police department ... and that of the public is to determine if that use of force was an appropriate response to the level of threat, disturbance and danger that they are encountering."

However, he is determined to meet the challenges, Bratton said.

The Los Angeles Police Department (LAPD) will create an "after-action report" to evaluate its handling of the event, and conduct a use-of-force investigation to determine if officers responded appropriately, he added.

Tuesday's rally by thousands of people calling for a path to citizenship for illegal immigrants was peaceful until about about 6 p.m., when police tried to disperse some demonstrators who had moved off the sidewalk into Alvarado Street in the downtown area.

Some demonstrators responded by throwing plastic bottles and rocks at officers, police said. Several dozen riot police, wearing helmets and carrying batons, fired a few dozen volleys of foam bullets into the crowd.

The clashes injured 15 police officers and at least 10 demonstrators.

The Radio and Television News Association (RTNA) said earlier that "there is evidence that officers knocked reporters to the ground, used batons on photographers and damaged cameras, possibly motivated by anger over journalists photographing efforts by officers to control the movements of marchers."

Gene Karpinski, president of the League of Conservation Voters, told the Times Giuliani's association with the law firm could cost him votes.

From clean air to mercury pollution to global warming policies, Giuliani's firm has been perhaps the most anti-environment voice in Washington, representing some of the biggest corporate polluters, Karpinski said.

Publicly however, Giuliani has advocated increased use of nuclear power, natural gas, Alaskan oil drilling and ethanol to reduce U.S. reliance on foreign oil, the report said.

"We are very encouraged by the Supreme Court's decision," Jeffrey Citron, chairman of Holmdel, New Jersey-based Vonage, said in a statement. The ruling "should have positive implications for Vonage and our pending patent litigation with Verizon," he said.

The high court devised a new test for determining when an invention is too obvious to warrant patent protection. The ruling makes it harder for those applying for patents, as well as patent holders seeking to win infringement lawsuits, to show they have developed a genuine innovation.

"There is no merit" to the Vonage request, John Thorne, New York-based Verizon's deputy general counsel, said in a telephone interview. "It's a delaying tactic to avoid final resolution of the appeal."

Yesterday's Supreme Court ruling concerning patent validity overturned a decades-old test used by the Federal Circuit. The case centered on the requirement that an invention be "non- obvious" and not simply combine prior inventions.

Vonage was ordered by U.S. District Judge Claude Hilton in Alexandria, Virginia, to stop adding customers after losing the patent ruling. On April 24, the company won its request in the appeals court to continue business as usual while it appeals.

The appeals court, which specializes in patent law, has set a June 25 hearing to consider Vonage's bid to reverse the jury verdict.

The journal would give credibility to a new business news channel that Murdoch's company, News Corp, plans to put on cable television later this year.

News Corp's bid is worth about 65 percent more than Dow Jones' recent market share. Many U.S. newspapers are losing readers and advertisers to online news sources.

The most recent study shows U.S. newspaper circulation falling more than two percent over the past six months.

An early version of the March order had authorized the officials to act without even having to consult the Attorney General, but the wording of the instrument was later revised at the urging of the DOJ Office of Legal Counsel, which was concerned about the constitutionality of such broad-brush delegation of power. An unnamed "senior executive branch official" quoted by the National Journal said of the order that it was "an attempt to make the department more responsive to the political side of the White House and to do it in such a way that people would not know it was going on." Senate Judiciary Committee Chairman Patrick Leahy (D-VT) expressed similar concern over the root strategy apparently reflected in the order, saying in a statement Monday:

This development is highly troubling in what it seems to reveal about White House politicization of key appointees in the Department of Justice. The mass firing of U.S. attorneys appeared to be part of a systematic scheme to inject political influence into the hiring and firing decisions of key justice employees. This secret order would seem to be evidence of an effort to hardwire control over law enforcement by White House political operatives.

Leahy called for the order and its supporting materials to be formally turned over to the Senate and House Judiciary committees looking into the US Attorney firings.
