alleges that the scent line-up was “rigged to be result-oriented, that is, to maliciously and intentionally implicate” [Calvin] Miller.
“…The forensic protocol and methodology used by Defendants rendered the scent line-up not only unreliable but so tainted and cross-contaminated as to be consciously indifferent to the rights of Plaintiff,” the suit states. “Mr. Pikett, the supposed K-9 expert, advised and participated in every flawed procedure used.” The suit suggests those procedures in effect helped deny Miller’s 4th Amendment rights.
I'd never heard of scent lineups before recently, but this appears to be another forensic practice that's accepted by Texas criminal courts but has never been subjected to rigorous scientific scrutiny. DNA exonerated the latest defendant after Pikett's dogs accused him.
