That's true but I don't see how it negates my point.

Do you go around telling people they should be worried about shark attacks, because someone could put a shark in their pool without telling them?

shark attacks in pools never happen where as abduction by strangers does.

Just because something happens at a lower frequency than something else doesn't mean we shouldn't protect against it or that it is not a danger to a particular person.

The fact that most abductions happen by family members has nothing to do with OPs point.

This is some kind of bias, the reason this is true is because it’s far easier for those people to abduct a child whose habits they know well. Now that the technology to track anyone is far easier to come by, maybe that will change.

No, that is not the reason. Most children are abducted in some kind of custody dispute, by someone who believes that they already have some kind of rights over the child.

Human trafficking is a huge problem even in America. This includes many children sold for sex. They often find and groom victims online now though, so yes, perhaps they aren't hiding in the bushes.
