No free man shall ever be debarred the use of arms. The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.

Southfield Mayor Brenda Lawrence is the only member from Michigan (so far) of the Mayors Against Illegal Guns Coalition. Via The WaPo:

A new report from a national coalition of mayors urges President Obama to adopt dozens of reforms to help curb gun violence, including steps to crack down on problems at gun shows and the creation of a federal interstate firearms trafficking unit.

The "Blueprint for Federal Action on Illegal Guns," a copy of which was obtained by The Washington Post, presents 40 recommendations that "would dramatically improve law enforcement's ability to keep guns out of the hands of criminals -- and, in doing so, save innocent lives."

The strategies outlined by the Mayors Against Illegal Guns, a bipartisan group of about 450 mayors nationwide, focus on the federal Bureau of Alcohol, Tobacco, Firearms and Explosives. The agency, which has been sent a copy of the report, declined to comment.

And of course the Federal Government through the ATF will expand it's authority (emphasis added):

The report also calls for a better approach to crime gun tracing, the process that tracks a seized weapon back to its first retail sale. The ATF lacks the structure or resources to "fully realize its power," the report says, and information is not regularly shared with field offices, and state and local law enforcement.

To this end, the study wants ATF to be funded to create a new "Office of Tactical Trace Analysis," which would replace the current crime gun analysis branch.

Because serial numbers are sometimes obliterated on crime guns, the study also wants ATF to require that manufacturers stamp new guns with a second, hidden serial number.

Why is it so critical to trace a gun back to it's original point of sale? Would it be to hold the retailer liable? Just asking the question.

Proposed changes urge that the ATF be given additional manpower. The agency has about 2,500 agents spread among 22 field divisions, the study says, and lacks resources to effectively police gun trafficking across state and national borders.
