Even if we have the ability to defend ourselves....it is not a given that we will come out of something unscathed.
With all that you and your son deal with on a daily basis, thinking about self defense is not necessarily a natural thing to consider at any given point. Please do NOT think that you failed him in this. You did NOT.
Through every experience we have, there is a chance to learn from it. Of course when anyone is hurt as your son was, it is a rotten thing. But from this experience, if he is interested in learning self defense, then I would say go for it

Knowledge is power....and now you can move onward and upward.
