I saw fit to denounce the boy's killing as despicable the day it happened.

If we are following the situation, how can we fail to comment on an attempted kidnap of a younger son the previous day.
It is unlikely to be unconnected, but I have not made my mind up as you accuse.

Your statement "a revenge killing nobody sees fit to comment on" shows you have made your mind up, and is false in regard to no-one seeing fit to comment.
I did.
