"Michigan Moms Demand Action," which is calling on public policy makers to approve tougher gun regulations, is making its way to Michigan Governor Rick Snyder's office Tuesday.

The group says it will deliver more than 14,000 postcards to the governor, saying simply: "Not One More," which was the comment made by Richard Martinez, whose son was shot to death in the recent Santa Barbara tragedy.

Gun rights organizations say that adding more laws regarding guns does nothing to save lives and nothing to bring back those who have been killed, they only limit the ability of law abiding citizens to protect themselves.
