hey there aardvark
i will do my best to answer your questions -
1) "Why does New Mexico per, NMC 30-7-3, prohibit all Firearms in all establishments Licensed to sell Alcohol,regardless if they are loaded or not,except for a Concealed Handguns for those who have Concealed Handgun Permits?"
Why??? because cc holders were able to get it changed. i believe this statute was changed this year to include cc in restaurants that serve alcohol on premesis....the onliine statute may not show the new change.
i will look for it.
2) "Did something happen in an Alcohol-based establishment that promted the creation of this Law to make this action a Felonous Crime?'
nothing comes to mind, but i could be wrong. it has been this way since i moved here 6 years ago.
3) "Finally, does this prohibition apply to all establishments that sell Alcohol including Grocery Stores, Licquor Stores, etc.?"
YES YES YES YES!!! i can not emphasize this enough.
"consumption on premises" ie, bars,
"packaged sales" ie walmart, albertsons, walgreens, liquor stores, gas station minimarts.....ANYWHERE alcohol is sold.
in addition to the above you must pay attention to any signage that may be posted by the owner of ANY business or private property prohibiting firearms on the premises.
you are also not allowed to carry in casinos.
not to be picky, but this is actually a NM statue, not part of the NM administrative code.
