QuoteThere is conceal and carry here but every business and building has the no gun sign in Chicagoland so it becomes a crime if caught on premises with a concealed firearm.
In Florida (and yes, every state has their own gun laws so check before travelling) carrying concealed in a store that posts a sign is not illegal. Store owners can ask you to leave and/or not come back, but if you're carrying concealed they will never know unless you are forced to use your weapon in which case they may actually thank you. The State does list places that you aren't allowed to carry such as a court house, school, a place of nuisance and it's the only state that prohibits carrying a weapon in an airport terminal.
Another resource is a four part series starting on October 18, 2019 from Mike Adams. Good info.
