“Of particular relevance to the present case, the nature and circumstances of the defendant’s crime may make discounting to present value of only limited utility in assessing loss. Peel’s attempted blackmail of his ex-wife is a case in point. A blackmailer is apt not to stick to his deal with his victim but instead to come back for more later…, so that the initially intended loss is apt to understate the loss to the victim had the blackmail succeeded. True, if Peel were to give all the photos back to his ex-wife, as he promised to do, he could not have blackmailed her further. But there would have been no assurance that he would do that, since she didn’t know how many of the photos he had. And even if the blackmailer doesn’t return for more, the victim is apt to be in constant fear of such a return, adding to the cost of the crime.” J. Posner, United States v. Peel, 595 F.3d 763, 773 (7th Cir. 2010).
