Just today my rav related a story from over 20 years ago when he was assaulted by someone who could easily have killed him. A Hispanic Christian from his neighborhood to whom he had been friendly intervened and saved his life, driving away the mugger.
I’ve also had the fortune of being able learn one on one with two charedi rabbis, one Chasidic, one Yeshivish. The Chasidic Rebbe would go out of his way to greet and thank the non-Jewish police officers who would guard the shul. The Yeshivish Rav would repeatedly relates stories of how important it is to treat non-Jews with total respect and dignity.
