PHILADELPHIA — Philadelphia’s top prosecutor today criticized the state attorney general for dropping a corruption sting, and he also announced what he called “the first, but not the last” charges in the revived case.

District Attorney Seth Williams charged a former Philadelphia traffic court judge with bribery for allegedly taking a $2,000 Tiffany bracelet from a statehouse lobbyist.

He found no evidence of racial profiling and had no legal qualms about the case, both were concerns raised by state Attorney General Kathleen Kane when she abandoned the sting earlier this year. Williams and all of the targets of the investigation, including several lawmakers from Philadelphia, are black. Kane is white.

Thomasine Tynes, the former president of the city’s traffic court, surrendered to authorities this morning. She is charged with accepting the bracelet during a birthday lunch at the Palm Restaurant in 2011 with lobbyist-turned-informant Tyron B. Ali. Tynes has told The Philadelphia Inquirer, which first reported on the investigation, that she did not initially know the silver charm bracelet was valuable.

However, Williams said it came wrapped in Tiffany’s trademark blue box and a matching bag.

Ali was working undercover after being ensnared in a $430,000 nonprofit fraud case, so all of it was on tape.

“This case is press and play,” Williams said in response to questions about legitimacy of the confidential informant. “Press a button and listen to the tapes. Press a button and watch the video.”

Kane inherited the case when she took office, and dropped it amid concerns that it was poorly managed, targeted black officials and was unlikely to score convictions. Her spokeswoman declined to comment on Williams’ remarks.

“This is not our case, and the Office of Attorney General does not make a habit of commenting on other prosecutors’ cases,” spokeswoman Renee Martin said today.

Williams had challenged Kane to send him the file after she abandoned the case, and later hired two of her top prosecutors.

“We started with evidence of widespread, but supposedly not prosecutable, political corruption,” Williams said at a news conference. He said the case files offered “clear, convincing evidence — all on tape.”
