I was on the original committe back in the early 80s that drafted the "shall" issue permit system in Louisiana. Once in the Legislature, some anti gun politicians made changes that few liked or wanted. One of those is the "Must advise" clause.
It passed and now carriers must tell the home resident that they are armed and request permission to enter.
If one carries openly, there is no need to advise.
However most carriers fail to advise and I have yet to find anyone that the clause created a problem for in any way. After a review of the problems that caused carriers to lose their permit or have them suspended, I cannot find even one that was due to failure to advise.
I do not want to suggest people violate the provisions of the concealed carry laws in Louisiana. All people need to obey any law. I will say that concealed is concealed and unless you plan on taking your clothes off in a residence, the resident should not know you are armed. Still a personal choice.
