Earlier this year, Judge Renee Marie Bumb granted a temporary restraining order to keep parts of a gun ban law that was signed by Governor Phil Murphy last December. The law required patrons to avoid bringing concealed weapons to certain areas including day cares and parks. Casinos are part of the bill too, listed as a sensitive place and guns were barred from the premises. With the recent ruling by Bumb, guns would now be allowed back in gaming venues. However, New Jersey casinos are not going along with the ruling.
Each of the nine casinos in Atlantic City will not allow guns on site. Because the casinos are private property, they have the right to ban guns if they like. It is unclear how this will be enforced but we assume that casinos will utilize technology such as metal detectors to ensure that guns are not brought on-site.
