For someone to press charges against someone there must be a crime. Carrying a CW in an area that has a non-conforming sign does not constitute a crime. If you fail to leave after being asked then a crime of trespassing has occurred. I carry in a lot of businesses in the upstate area that have illegal signs. Haywood mall and banks are some examples. The way the law is written I don't worry about a little thing like a illegal sign.

To preserve liberty, it is essential that the whole body of people always possess arms, and be taught alike, especially when young, how to use them... -- Richard Henry Lee, 1787
