“Saying it’s legal to carry on grounds should be legaslitated to not be a lawsuit issue, like the castle doctrine laws.”
Apparently you are not aware of all the silly lawsuits about “negligence”, guns involved or (many) not.
Fact is that is how it is nowadays.
Until we change to “LOSER PAYS”, you concern yourself with all angles of liability.
In Texas, anyplace that doesn’t have a certain sign is legal to carry (more or less, besides education and bars and sports and other exceptions).
So all places *without* such signs are liable? I don’t think so.
