Stanley Springer is a spy shop owner who appeared in Escaped (episode).
Mickey Stokes purchased wiretap devices from him to prepare for the Greater Virginia Bank robbery and to bug Anthony DiNozzo's dictophone to stay one step ahead of the team while they pursued Derrick Paulson.
Timothy McGee brought Springer in for interrogation after Abby identified the bug in the phone. Springer was uncooperative; to avoid potential blowback from what his clientele did with his products, he had memorized countless legal documents that defended his rights, and was on his guard against answering any questions that could affect him. Ziva attempted to persuade him, and upon failing, Gibbs stepped in. Gibbs stated that he was trying to help a little girl get home to see her dad, and he needed Springer's help for that, finishing by saying "please." More subdued, Springer asked what they wanted to know. Gibbs showed a picture of Paulson and Mickey, upon which Springer identified Mickey as the culprit rather than Paulson, surprising everyone.
