If the Baby is ALIVE then it is. If the Baby is dead then they probably have a camera that can be used to IDENTIFY the person placing the Baby in the box.
Tragic for the baby and young mom. At least she didn’t toss it in the trash. She probably felt awful about the dead baby.
Other than a restroom there is really no place in any hospital in the US that isn’t under constant cctv surveillance, especially in the ER ambulance entrance, the ER , main and outpatient lobby and security personnel a;ll over the place.
No ... if there’s surveillance, there’s surveillance ... and it’s NEVER anonymous.
