In Pennsylvania, the law also provides civil remedies to victims of crime both against the perpetrator and others who negligently allow crime to occur on their premise or property within their control. The law requires private business operators and owners, who hold their business open to the public, to use reasonable care to protect their patron, while they are on the business premises, from physical harm caused by the accidental, negligent or intentional acts of third persons. To satisfy this duty, such businesses must satisfy their affirmative obligation to discover whether third party harmful acts are being done or are likely to be done. Where this is established, Pennsylvania law requires these businesses to give adequate warnings to their patrons to allow them to avoid such harm or otherwise protect themselves from such dangers. 18 Pa.C.S.
