Adware could have caused this.
Of course that brings us to the security team whose job it is to stop that, a team which consists of game warden Robert Muldoon. SPOILER: All of those people we just mentioned are quickly eaten by dinosaurs.

What the hell? Even smaller theme parks like Disneyland tend to have more security, just to keep toddlers from getting mangled by the Country Bears robots.
Why Some Extra Staff Wouldn't Have Hurt:
Instead of breeding more attractive, popular and harmless dinosaurs, John Hammond thought it might be a good idea to breed super-intelligent (and apparently pure evil) velociraptors, despite the fact that they would hardly have been an attraction since before 1993, only paleontologists and guys who regularly read the dictionary knew what they were.
Even stranger, they also don't appear to be part of the park's tour, and are instead quarantined to a Kafkaesque holding pen, where even just a brief sight of them feeding seems to be enough to cause Jeff Goldblum to completely lose his appetite.
