The lead from an AP story today: “A 15-year-old girl was raped while fellow students watched after being drugged at a weekend party, police said.”
Two commas would have made that sentence accurate. The AP could have taken the commas from this sentence in The Washington Post, making both sentences accurate:
“Business leaders are most worried about Sunday, because that’s the day the majority of Virginians, who are Christian, consider a religious holy day.”
