As verbal responses go, that's pretty mild, especially when the cop was injured and saw that he was about to be physically assaulted.
Of course, it is the cop, not the four year old, who is the victim.
I forgot, we must defend our government employees at all costs, Comrade.
After all, when it is your daughter, your niece, your granddaughter, or your female relative who lies bleeding, and the governement employee who struck her believes his *occupation* is more important justification to relate than a *fervent, sincere apology for causing a tragic accident*, at least you’ll have the satisfaction of saying:
“Oh, you’re a police officer, that’s different then. I thought you were a mere mundane who struck my daughter/granddaughter/niece/female relative.”
