Gun violence in Philadelphia has been rising, and this isn’t just limited to the city. This is a measure taken to ensure the safety of guests and employees. Any gamblers carrying guns aren’t allowed entrance to the casino. Security personnel also search bags for firearms. Lately, it has been using metal detectors, and it funnels visitors through them at all three entrances. For many years, Parx Casino has posted signs asking its customers not to enter the property carrying guns.
