Word of warning: Don’t let any rescue workers onto your property. Especially if the situation requiring emergency intervention could be hazardous to the health of the rescuers.

Seems a one-year-old baby named Joey Cosmillo wandered into the backyard of his central Florida home and fell into the pool. By the time his mom got him out, he wasn’t breathing. Rescue workers managed to resuscitate him. But the child is now brain damaged.

A terrible tragedy for any family. But now, add to that trauma a lawsuit from a police officer who showed up on the scene in response to the 911 call. Sergeant Andrea Eichhorn slipped on a puddle of water in the home that day, and broke her knee.

The sergeant isn’t talking to the press. But her lawyer explains: “It’s a situation where the Cosmillos have caused these problems, brought them on themselves, then tried to play the victim.”

I guess the lesson is, don’t call firefighters if your home is on fire. They might get burnt. Don’t call the police on your cell phone if you’re a hostage in the middle of a bank robbery. They might get shot at. Don’t call anybody who makes a living dealing with dangerous situations if you’re in a dangerous situation and can’t make everything normal before the cavalry arrives.

Of course, most emergency personnel have more common sense and good will than this. But you know, just when you think you’ve heard everything . . .

This is Common Sense. I’m Paul Jacob.
