Parsons Brinckerhoff examines a 13 statements published by Wendell Cox Consultancy (The Public Purpose) and concludes (erroneously):

In every instance, Cox's statements are either inaccurate, distortions or claims not supported by the facts.

In fact … Parsons Brinckerfoff falls far short of proving any of its allegations by any reasonable standard. This leads to a concern on our part that Parsons Brinckerhoff does not intend to make a good faith contribution to the public debate and is maliciously inclined with respect to Mr. Cox.
