A Regal theater I went to a few had the exact same poster.
I suspect that there is probably a handful of regal theaters that have big problems and so they did a blanket poster for all banning guns but now it covers ALL theaters where law abiding and good people go where nothing happens.
As was stated in another thread.... there is no exception for off duty police so I guess they do not want anyone there with guns. So it is a gun free zone and we all know that this equals.... easy target.
Some theaters do not ban guns... So let me say that my wife and I CC in all the theaters we visit...
