Mr. Harrington thinks that the dad should have summoned just the right amount of anger and aggressiveness to defend his daughter from a physical attack, but not go too far. Hmmm, maybe the dad should have paused to assess his physical strength versus that of the molester, asked the molester if he had any ailments that could make death more likely in a fight, agree to some rules, and then proceeded. This sounds like the dad is Israel, and Mr. Harrington is the U.N., demanding a perfect “proportional response”.
This was the perfect proportional response.
