Yes, the predators are everywhere.  Your children are not safe with anyone or anywhere.  Alarmist?  No, realist. 

Take this story of Robert A. Singer, COO of the National Children's Museum, being charged for child pornography.

The images sent from Singer's museum computer depicted sexual acts between minors and adults, the complaint said.

Just imagine all the public school children who have been corralled onto busses and taken to this "safe" place, with limited supervision by strangers.  I cannot believe that parents are still placing their children in these situations, knowing what we know now about the perversion of our culture.

Homeschoolers, you are right to suspect every staff member of every museum, school, camp, league, or program -- Christian or secular.  None of these people love your children as you do.  Only your direct supervision can protect your children from these predators. 

I don't care if I am casting aspersions on some good people who might work with children.  I would not risk my child on the chance, nor should you.
