I don't know of anyone who's been attacked by a coyote, child or otherwise. I don't hear of livestock being killed. Of course, deer are extremely plentiful here, so perhaps they are content to stick with those. And personally, more power to em' in that regard.
Now remember...I live in an agricultural community. If livestock predation by coyotes were a big issue, it would be well known. I just don't believe that, in my area at least, they are any kind of threat to people. As far as pets, yeah I believe that coyotes are opportunists and will grab a meal where they can take it. The same way a hawk or an owl will take a chicken.
