So much for President Obama's plan to win support for his gun control measures from the nation's top law enforcement officials.

Joining two police organizations that slammed state and federal anti-gun efforts, the West Virginia attorney general is warning that he will fight any new law--just like several states tried to do when Washington passed Obamacare.

West Virginia Attorney General Patrick Morrisey said that he will fight a federal ban on assault weapons like the one being pushed by California Democratic Sen. Dianne Feinstein.

"If a federal law is enacted that is similar to Senator Feinstein's legislation, the West Virginia Attorney General's office would actively participate in legal efforts to ensure that such law does not infringe upon the rights of West Virginians," Morrisey said in a statement. He added: "These efforts may include a wide range of legal and educational actions."

The Charleston Gazette said the new attorney general has created an Office of Federalism to challenge Washington's laws like the proposed gun ban.

Secrets reported late Tuesday that the Southern Police Benevolent Society, part of the national Police Benevolent Society, said in a statement that the federal assault weapons "will do nothing" to stop gun crimes, even those against police.

The County Sheriffs of Colorado said that gun control plans are being drawn up in haste and that the public should not be robbed of access to assault-style rifles, high-capacity magazines, bulk ammunition and private gun sales.

"New legislation aimed at reducing or restricting law abiding citizens from purchasing or owning firearms will do nothing to reduce violent crime nor will it stop criminals or those who want to commit evil acts from obtaining weapons," said the president of the 30,000-strong Southern Police Benevolent Society, Chris Skinner.

The statements are a blow to the president, especially when added to other law enforcement groups that have stated their opposition to gun control efforts.
