As federal and local officials in Wisconsin learn more details about the deadly shooting at a Sikh temple, the city is stepping up security and speaking out against the violence.

Mayor Michael Bloomberg and Police Commissioner Ray Kelly were joined by leaders in the Sikh community in Richmond Hill, Queens on Monday afternoon to condemn the shooting.

While Kelly says there is no specific threat to Sikh temples in the city, the NYPD has deployed additional resources, including members of its critical response unit on counter terrorism.

The mayor says there's no room for gun violence in the city.

"We have no tolerance for intolerance or for lawless violence," Bloomberg said. "They go against everything that New York is all about and this remains a city where people of every nationality live in harmony, and where people of every faith worship in freedom, and that's essential to who we are as New Yorkers."

Commissioner Kelly also said a Wisconsin police officer shot nine times at close range in the tragedy is the brother of a recently retired NYPD detective. He was listed in critical condition on Monday.

Kelly says the department will be in touch with the FBI and other law enforcement officials to monitor for any threats.

Bloomberg also used the opportunity to once again criticize both President Barack Obama and his Republican rival Mitt Romney for not addressing gun violence on the campaign trail.

"Still the two presidential candidates have not given the American people a plan to keep guns out of the hands of dangerous people,” Bloomberg said. "Deafening silence, I think, is a fair ways to phrase it,” he said.

Bloomberg's trip to the Sikh temple followed the release of an ad Sunday by his anti-illegal gun coalition, Mayors Against Illegal Guns, that stars some of the victims of the Arizona shooting of former Congresswoman Gabrielle Giffords.

"Our leaders gave us a moment of silence then, but they haven't given us a plan. President Obama, Governor Romney, we demand a plan,” the victims say in the ad.

Bloomberg also used the opportunity to clarify his own position. He said his administration is not about gun control but they are about crime control and curbing ownership of illegal guns and assault weapons.

"We are actually on the forefront, I think, of crime control and guns, I think, are the reason why we have high crime,” he said.

But before his temple visit, the mayor defended the Second Amendment at a park opening in Far Rockaway.

"Guns, you have a right to carry by the Second Amendment. The courts have said that municipalities, states and the federal government have the right to enact reasonable protections for the public,” Bloomberg said.

The mayor also defended the city's sale of spent city police shell casings to a Georgia ammunition store, and said such a sale could happen again.

"It's not ammunition. It is scrap metal. The law says we have to make the scrap metal available to anybody who wants to buy it and take the best price,” Bloomberg said.

Later in the day, several other local politicians joined Hindu and Muslim groups at the same temple to condemn the shooting and express their support for the city's Sikh community.

"What happened in Wisconsin was a terrible reminder that there is still bigotry of the worst kind," said City Comptroller John Liu. "And often times that bigotry is directed towards Sikhs, towards immigrants, towards racial minorities and it has to be stopped."

"When violence happens, we know that the best way from Gandhi to deal with violence is to express more peace, more God, more love, more compassion for those that have been hurt," said Queens Councilman Ruben Wills.

Meantime, authorities released more details about the suspected shooter.

Police in the Milwaukee suburb of Oak Creek identified the suspect as 40-year-old Wade Michael Page.

They say he served in the U.S. military from 1992 to 1998, had a general discharge and was not eligible for re-enlistment.

A civil rights group described Page as a "neo-Nazi" who used to play in white supremacist punk rock and metal bands.

Authorities say Page was acting alone when he opened fire on Sunday at a temple in Oak Creek, killing six worshippers.

The city's police chief says five men and one woman were killed, ranging in age from 39 to 84.

Two other people were also listed in critical condition on Monday.

ATF officials say the gunman used a 9 mm handgun and multiple magazines of ammunition, and they say the gun was purchased legally.

"Sunday was a tragic day for our city, especially given the fact that it occurred in a place of worship at a Sunday service, on a quiet Sunday morning in Wisconsin. Our thoughts and prayers go out to the families of the victims, for our wounded officer, all our responders, fire, police, other agencies, and the community which is still in shock," said Oak Creek Mayor Steve Scaffidi.

A candlelight vigil was held in Milwaukee on Sunday night in memory of the victims.

Oak Creek's mayor says another vigil is planned in the city for Tuesday night.

In a statement, President Barack Obama said he was deeply saddened by the shooting.

The Asian American Legal Defense and Education Fund also condemned the shooting, saying Sikhs are increasingly victims of violence and discrimination in the U.S.

According to the Sikh Cultural Society, there are nearly 100,000 Sikhs living in New York City.

The 500-year-old religion preaches equality and peace.
