If you are related to X people then the odds that one of them attacks your child is greater than that anyone else on the planet.
Picking numbers from thin air:
Let's say are related to 30 people know 200 and you encounter 10,000 random strangers and you have a 1 in 100 chance of an attack. Well the odds a specific random stranger attacks your child given the above assumptions is less than 1/2,000,000. The odds a specific person they know attacks your child would be less than 1/20,000 and the odds that a given relative attacks your child would be more than 1/6,000. Now who would you focus on? (What about a predator that has a 50% chance of attacking someone well he is still under 1/6000 because there are so many other people for them to attack.)
PS: Given my child's particular environment you should focus on relatives and people you know.
