You both said it perfectly. But this was always going to happen. Sinn Fein/IRA cannot do this publicly so they get their apologists to harass the widow and sisters of a man not just murdered, but butchered like an animal by the IRA.
The irony is the family were previously Sinn Feinn voters and did not not complain when Protestants or Britons were similarly slaughtered by the IRA.
Watch the movie Michael Collins. There was once a good reason to fight.
But nations evolve. And that antipathy should have faded away. When you start targeting innocent people, there's a problem.
