If there really are neighbors that will write affidavits stating that CWW was at home that weekend wouldn't a good attorney get them to sign those affidavits ASAP. That to me is the biggest hint that there really isn't any neighbor going to say CWW was at home that weekend. He talks in future tense of getting these affidavits. IMO one of the first things an attorney would do is get those affidavits signed in case the witness changes their mind about wanting to do it. My gosh this is his clients best alibi, and she hasn't done it yet!IMO - CWW was blowing smoke, he planned to use this argument to fight extradition too. There may be a pen shortage in the 'hood, since none of those letters ever appeared and CWW is now a guest of Fl LE. Shows us a little of how arrogant he is though, he presumed that his neighbours would do it just because he said they should/would.
My suspicious mind thinks that maybe it is all part of the plan. Float the theory now that there are ones that saw CWW in town that weekend, then later say the are to afraid to come forward.
