Wisconsin is one of two remaining states where concealed carry by ordinary citizens is still illegal. Open-carry is legal except where prohibited by law (government buildings, schools, and places that sell liquor), but, in the words of one Wisconsin resident, "you will attract the attention of every police officer in the area." Some jurisdictions have tried to prosecute open-carry by equating the open carry of handguns with Disorderly Conduct. Inside vehicles, the firearm must be both unloaded and encased; having a loaded firearm on the front seat was held to be concealed and therefore illegal in a 1994 case. Bills to enact shall-issue were twice vetoed by Governor Jim Doyle in January 2004 and again in January 2005 after passing in both houses of the Wisconsin legislature. In 2005, the Assembly fell two votes short of overriding Doyle's veto.
