MILWAUKEE (AP) -- Gov. Scott Walker signs a concealed-carry bill into law this week. When he does, city officials and businesses around the state will have about four months to figure out how to comply while also keeping citizens and customers safe.

Law enforcement agencies will need to prepare for the possibility of more people carrying hidden guns. Businesses will have to choose whether to ban concealed weapons on their premises at the risk of alienating gun-supporting customers. And organizers of public events will have to decide whether to keep guns away when alcohol is served.

However, even as questions linger, gun-rights activists say there's little reason to worry. They say 48 other states already have concealed-carry laws, and none saw any major increase in gun violence after its laws took effect.
