obama campainged on this,
“”We cannot continue to rely only on our military in order to achieve the national security objectives that we’ve set,” Obama said in July. “We’ve got to have a civilian national security force that’s just as powerful, just as strong, just as well-funded.”
In late spring the House passed a bill that set this in motion. when not being used for national emergencies ( not to be confused with the National Guard helping with floods, fires etc) this federal force would be farmed out to local police and /or US Marshalls. IIRC the initial force would be 6,000. I will try ti find the link
"A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed."
