Q. On so many levels it seems true journalism is dead, but what required reporters to take out the English language with them? I refer to the constant phrasing similar to the following: “The defendant PLEADED not guilty at the arraignment.” Have these people never seen or heard the word “pled,” or did I miss a memo?

A. Sorry—you missed the memo. (You can also check usages like this in a good dictionary.)
