Does it take a year or three to walk to the school library? If they're young enough that that isn't the easier option, then there's no way they're capable enough to execute a relatively complex technical exploit.

I'm not telling not to worry about your kids' safety. I'm telling you not to worry about them dying from a lightning strike because they walk to school next to a 6-lane road full of drunk drivers every day. If they're going to get hurt, it won't be through the most complicated and least-likely way possible.
