NBC’s long-running crime drama “Law & Order: Special Victims Unit” featured immigration officers blocking the police from investigating a rape by trying to arrest an illegal immigrant witness. Thursday’s episode, “In the Wind,” followed a building superintendent named Jorge Ruiz, played by Juan Francisco Villa, who becomes a key witness in identifying a rape suspect. However, Ruiz’s illegal status complicates matters after he flees an Immigrations and Customs Enforcement (ICE) raid on his building because of his past as a convicted felon.
