If you go back to the original Reuters article[1] (first link from your Wikipedia aritcle), there's a few nuances that most people bringing up parallel construction don't point out: (emphasis mine) "...Today, the SOD offers at least three services to federal, state and local law enforcement agents: coordinating international investigations such as the Bout case; distributing tips from overseas NSA intercepts, informants, foreign law enforcement partners and domestic wiretaps; and circulating tips from a massive database known as DICE. ... ...Wiretap tips forwarded by the SOD usually come from foreign governments, U.S. intelligence agencies or court-authorized domestic phone recordings. Because warrantless eavesdropping on Americans is illegal, tips from intelligence agencies are generally not forwarded to the SOD until a caller's citizenship can be verified, according to one senior law enforcement official and one former U.S. military intelligence analyst."
