HB 2664 provides a defense to prosecution if a concealed handgun license holder carries a concealed handgun into an establishment that gets 51 percent or more of its income from the sale of alcoholic beverages, but has failed to post the statutorily required notice that it derives 51 percent or more of its income from the sale of alcoholic beverages. (Under current law, a concealed handgun licensee can be charged with a Class A misdemeanor for doing this.) http://www.txdps.state.tx.us/director_staff/public_information/pr081109.pdf Could someone remind me what "defense to prosecution" is. I didn't know that bars were required to post 51% signs. I've seen a lot of places that had liquor lisences of "sign = red" that didn't post a 51% sign.
