Finding Peer-to-peer infringers unreliable?

So says this attorney in response to the RIAA Dear RIAA:

I know of no facts on which a good faith finding of probable cause by either your clients or your law firm could be based to support a claim for relief against Mr. Merchant.

It is well documented that your clients' reliance on MediaSecurity (an admitted "non-expert;" UMG v. Lidor, East Dist NY No. 1:05-cv-01095-DGT-RML) and its overall method of identifying P2P copyright infringers is wholly unreliable and inadequate. See, e.g., February 23, 2007, deposition of the RIAA's expert. http://www.ilrweb.com/viewILRPDF.asp?filename=umg_lindor_070223JacobsonDepositionTranscript.
