More Cry Than Wool Meaning

(idiomatic) Dramatic assertions backed by little evidence

Example: 1747, John Smith, Chronicon Ruſticum Commerciale; or, Memoirs of Wool, &c., London: T. Osborne, page 304:
  TheÅ¿e are the Crimes of which we are guilty, before any Law to prohibit us: it were more allowable to plant PoiÅ¿on than to Manufacture with us, and we lie, it Å¿eems, under Å¿uch an Obloquy and Clamour, (which, as far as I can judge by your Letter, you alÅ¿o liÅ¿ten to) that, as to import our Cattle to you is a NuÅ¿ance, and to export our Wools is Felony ; Å¿o, by Gradation, to erect here a Manufacture ought to be no leÅ¿s than TreaÅ¿on. And yet there is more Cry than Wool in all this Matter : For I dare, and do aÅ¿Å¿ure you, that, modeÅ¿tly Å¿peaking the whole Quantity of what we work up in Ireland, amounts not to the Half of what any one Clothing-County in England does.
1999 February 26, Selya, Bruce M., “Aguilar-Solis v. INS”[1], 1st Cir. 1999, case no. 98-1484:
  In rebuttal, the petitioner offers more cry than wool. He points first to the vague threats that his family and friends relayed to him during his 1990 return to El Salvador, and speculates that members of the FMLN still sought to harm him at that time. This is unabashed surmise.
