Nebraska lawmakers have advanced a bill that would prohibit most weapons and certain substances from being brought into the State Capitol building. The bill, LB1237, aims to enhance security by directing the Nebraska State Patrol to implement screening procedures by 2027. Exceptions are included for law enforcement officers, individuals with concealed handgun permits, and those with prior approval. The measure defines prohibited weapons and substances, with amendments addressing concealed carry permits and penalties. Supporters argue the bill is necessary to protect Capitol employees and visitors, while opponents raise concerns about public access and individual rights.
