The Arizona senator reminded the National Sheriffs' Association that the next president will nominate hundreds of federal judges and that these personnel decisions “will have far-reaching consequences for all Americans, and perhaps especially for law enforcement."

“When a serious crime is investigated, prosecuted, and punished, it takes many hours and the best efforts of police, trial courts and juries,” McCain stated. “Yet one badly reasoned opinion, by one overreaching judge, can undo it all. Just like that, evidence of guilt can be suppressed, or a dangerous predator released because of judge-made laws having little or nothing to do with the requirements of the Constitution.”

The Republican standard-bearer stressed that the makeup of the Supreme Court is especially important because it sets precedents that could “add one more obstacle to the work of law enforcement.”

In his remarks, McCain used one of the high court’s rulings last week to warn of an “Obama Court.”

While he acknowledged that the Illinois senator joined him in opposition to a ruling that those convicted of raping children should not be subject to the death penalty, McCain argued that this “was exactly the kind of opinion we could expect from an Obama Court.”

He also used the case to criticize the Democratic presidential candidate for opposing the nominations of Chief Justice John Roberts and Associate Justice Samuel Alito.

McCain argued that the majority in the case “substituted their judgment for that of the people of Louisiana,” adding that “there is nothing in our Constitution” that contradicts the law.

In blasting the decision, the Republican also stated that he supports tougher laws against convicted sex offenders.

McCain said that those convicted of sexual assault against a child, after being released from prison, should “be tracked both in their physical movements and in their Internet usage.” He added that “anyone who uses the Internet in the commission of a crime of child exploitation is going offline and into prison for an additional 10 years.”
