Sen. John McCain (R-Ariz.) on Sunday urged states to review their "stand your ground" laws amid a widening debate over the Trayvon Martin verdict and racial profiling.
About two dozen states have laws that allow individuals to act in self defense during a conflict without attempting to retreat, including Arizona. A Florida jury's acquittal of George Zimmerman in Martin's killing has renewed debate over those statutes.
McCain said he "trusts the judgment" of the jury that acquitted Zimmerman, but said that "stand your ground" rules need a second look.
Protests are scheduled around the country this weekend as supporters of Martin's family cope with the verdict.
Demonstrators are also urging the Justice Department to mount a federal civil rights case against Zimmerman, an outcome that experts say is unlikely.
McCain said he and others were "probably too optimistic" that racial prejudices would lessen after President Obama's election in 2008.
"Old prejudices die hard, especially in hard economic times," McCain said. "We've got a long way to go."
