In his recent perspective piece, What if Mueller Hadn’t Been Appointed? (N.Y.L.J., July 31), Joel Cohen observes that matters would have been worse if the investigation into President Trump had not been conducted by special prosecutor Mueller but rather by an ordinary line prosecutor, the hypothetical James Straight.

True. But matters would have been better if the investigation had been conducted by a true independent counsel, call her Jane Arrow, appointed on the model of the post-Watergate statute that Congress passed in 1978.
