Updated: Report: Police May Have Stopped Plot to Kill Obama

Update This appears to be a less credible threat than early reports indicated.

This may be nothing more than a couple of meth-heads getting busted -- an everyday occurrence in America.

According to a report in the Rocky Mountain News:

Authorities are investigating a possible threat against presumptive Democratic presidential nominee Barack Obama.

Aurora police arrested a longtime drug user Sunday afternoon during a routine traffic stop where the man was seen "weaving," sources said. Two possible other accomplices also were arrested, according to police.

Police found four weapons, including two rifles and two handguns, in a rented pickup.

That arrest then led authorities to a second man staying at the Cherry Creek Hotel at 600 South Colorado Blvd in Glendale. When authorities knocked on the man's door, they say he jumped out of his sixth floor window, landing on an awning and running from the scene. They say they soon found him with a broken ankle. He too was arrested.
