WASHINGTON (CNN) - Attorney General Eric Holder stepped up his call for the passage of federal hate crimes legislation Thursday, arguing that the federal government needs to address a rising tide of criminal activity fueled by bias and bigotry.
Holder made his remarks during testimony before the Senate Judiciary Committee, which is currently considering the Matthew Shepard Hate Crimes Prevention Act.
The bill would allow the Justice Department to provide assistance to state and local authorities in the prosecution of hate crimes, while also expanding federal protection against hate crimes to cover disability, gender, and sexual orientation.
"Hate crimes victimize not only individuals but entire communities," Holder said.
"Perpetrators of hate crimes seek to deny the humanity that we all share, regardless of the color of our skin, the God to whom we pray, or the person who we choose to love. ... The time is now to provide justice to victims of bias-motivated violence and to re-double our efforts to protect our communities from violence based on bigotry and prejudice."
The attorney general argued that "recent numbers ... suggest that hate crimes against certain groups are on the rise, such as individuals of Hispanic national origin."
Specifically, he said, more than 77,000 hate crime incidents were reported by the FBI between 1998 and 2007, or "nearly one hate crime for every hour of every day over the span of a decade."
The FBI, Holder added, reported 7,624 hate crime incidents in 2007 - the most current year with complete data.
In light of such statistics, he said, it was one of his "highest personal priorities ... is to do everything I can to ensure this critical legislation finally becomes law."
Republicans on the Judiciary Committee disputed Holder's assertion that there has been a noticeable increase in the number of hate crimes. They also questioned the need for federal involvement in the prosecution of violent acts - traditionally a function of state and local governments.
"I think the FBI statistics would show that hate crimes have declined over the last ten years," said Alabama Sen. Jeff Sessions, the committee's ranking Republican.
It is also "important to know (if) we have a problem of significant numbers of (hate crime) cases ... not being prosecuted in state and local governments," he argued.
"Murders occur all over America every day. Robberies, assaults, rapes, burglaries occur every day, and those are handled by our state and local jurisdictions. ... They do a pretty good job."
Sen. Orrin Hatch, R-Utah, argued that there is little evidence of a failure among state and local officials to prosecute violent crimes motivated by bias or hatred.
"I haven't seen it" as a major problem, he said.
Holder replied that while state and local governments generally do a good job prosecuting violent crimes, there is nevertheless a need for federal involvement on occasion, particularly if localities lack the resources for an effective investigation or prosecution.
He also asserted that any federal hate crimes law would be used only to prosecute violent acts based on bias, as opposed to the prosecution of speech based on controversial racial or religious beliefs.
Several religious groups have expressed concern that a hate crimes law could be used to criminalize conservative speech relating to subjects such as abortion or homosexuality.
The attorney general has been a vocal proponent of federal hate-crimes legislation since his tenure in the Clinton Justice Department. Last week, in a speech on civil rights, he cited three recent fatal shootings in calling for stricter hate crimes laws.
"The violence in Washington, Little Rock and Wichita reminds us of the potential threat posed by violent extremists and the tragedy that ensues when reasoned discourse is replaced by armed confrontation," he said.
Holder was referring to the shooting death of a security guard at the Holocaust Memorial Museum in Washington, allegedly by a self-avowed white supremacist; the shooting of two U.S. soldiers in Little Rock, Arkansas, allegedly by a man prosecutors say was targeting the U.S. military for what it had done to Muslims; and the murder of a doctor who ran a women's clinic in Wichita, Kansas, allegedly by an abortion opponent.
