"The people living at this address might be pedophiles and sexual predators. Not saying that they are, but if your children are in the vicinity, I strongly suggest you get them back to safety."
Still asserts that in that house there may be sexual predators. If I lived in that house I wouldnt be happy, and I would want a way of clearing the accusations and proving that there are indeed no sexual predators in my house quicksmart before other people start avoiding it.
I think that might count as libel.
