An interesting quote from the article (emphasis added)...
"Wisconsin laws are very weak when it comes to the illegal carrying of firearms," Flynn said. "Most of our violent offenders have criminal records. For them, it is more dangerous to get caught without their gun than to get caught with it. We have not yet succeeded in altering their mental calculation."
Is it me or does it seem like some people are finally starting to realize that the gun does not cause the crime, people do.
