Michigan Sets an Example
In
January 2008, the Detroit Free Press ran a detailed story about how the state’s
progressive concealed carry law had actually resulted in lower crime and even a
reduced incidence of suicide. Gun control proponents frequently predict increased
violence and a rise in suicide with passage of concealed carry statutes.

I have to agree that Michigan has set an example.
At the very least, criminal misuse of firearms hasn't increased since the CCW went from "may-issue" to "shall-issue" in 2001. As the news article cited indicates, reported criminal misuse of firearms has decreased marginally.
It might be within the region of statistical noise. Or it might not.
Apparently, the a statewide increase in concealed-carry-permit-holders hasn't done anything to increase criminal misuse of firearms.
However, it is not the guns that make people safe. It is proper use of guns that make people safe.
