Apparently, those who would wreak havoc upon others are also illiterate... or he just ignored that sign on February 12, 2007. That was when Sulejman Talović went on a shooting spree at Trolley Square Mall, killing five people and injuring four more before being shot to death by an off-duty police officer. Randomly killing folks is a violation of law, whereas ignoring a property policy means "jack schitt"! Was that sign any kind deterrent? Hell no! How many more would he have killed/injured if that LEO hadn't been there at that point in time... and how many less if more people had been armed at Trolley Square Mall? Pax...
