It will still take down most of the no-guns signs. The reason so many shopping malls and other public establishments have a no-guns restriction isn't because they don't like guns themselves per se, but because the insurance companies all require a no-gun policy as condition of getting liability insurance.
The new law is basically a civil suit safe-harbor exemption that says that the business owners cannot be sued for the use of a legal firearm for self defense or other justifiable purpose on their premises.
Insurers no longer have a need to force blanket no-gun requirements in their insurance policies.
That makes sense. Thanks for the translation.
I think businesses that ban firearms should be considered negligent at the least, if they do not have armed security.
