No. However, the police are quick to respond if the clinic calls (but not if a pro-lifer calls to report
he's been assaulted) and are so biased against pro-lifers that the city is being sued in federal court for civil rights violations. There are cameras and embedded microphones at the location and the owner lives there and is armed.
But no, there aren't security personnel on site. That would cut too far into the profit margin, I'm sure.
