According to the Dallas Morning News, if House Bill 1177 becomes law, any Texan who legally owns a firearm could carry their handgun, open or concealed, for a week after a state or natural disaster is declared.
Critics of the bill worry the bill would present difficulties for police working after a hurricane or other disaster.
