The tv piece I saw on NBC11 earlier seemed be by a PD spokesman and he made reference to the full-auto capability, as opposed to semi-auto fire. Also referred to the Northridge CA robbery incident from a few years back. It sounded like the speaker knew the diff btw fuul & semi auto. This IS Texas, after all! ;)
Hope they catch these cretins. I know that the fine Citizens of Texas won't panic and holler for a renewal of the AWB because of this incident.
