I know Corry dislikes internal capitalization, but for goodness sakes, "Mynypd" instead of "myNYPD"???? NYPD is an initialization, for goodness sake. You are supposed to capitalize it in standard orthography. And why would you capitalize the "m" in "my"? The hashtag isn't a proper noun.
That being noted, the myNYPD hashtag is a terrific own goal. What did they think would happen?
