They didn't say specifically, they just cited a vague state law about discharging firearms. I didn't look it up yet but basically the kind of law where they "could" cite you if they wanted. I am going to do research on it tomorrow. I do suppose they could always hang you by using the noise ordinance though.
Ok thanks.
He's the laws if you want to keep them for the future to look up stuff. http://legis.la.gov/Legis/Laws_Toc.aspx?folder=75&level=Parent
