Two Atlanta cops are headed to prison in the Kathryn Johnston killing, an NYPD narc goes down for drug running, and a strung-out Pennsylvania cop heads to jail for peddling pills. Let's get to it:

In Atlanta, two Atlanta police officers were ordered Monday to report to prison to begin serving their sentences for their roles of the killing of 92-year-old Kathryn Johnston in a drug raid gone bad a year ago this week. In that incident, the officers involved lied to a judge to obtain a search warrant for Johnston's home, shot at her 39 times after she shot once at them as they broke her door down, planted marijuana in her basement, and tried to get an informant to say he had provided the information for the warrant. No drugs other than the planted pot were found at her home. Officers Jason Smith and Gregg Junnier pleaded guilty to voluntary manslaughter and other state charges and to federal allegations of conspiracy to violate a person's civil rights ending in death. They have been cooperating with federal authorities in an ongoing investigation into the incident and broader issues of misconduct in the Atlanta narcotics squad, but now a federal judge has ordered them to report to prison by December 3. They have not yet been sentenced, but in their plea bargain agreements, the deal was that Smith would get no more than 12 years and Junnier no more than 10, with possible sentence cuts depending on their degree of cooperation. A third officer involved in the incident, Arthur Tesler, faces state charges. His trial will probably begin in April.

In New York City, an NYPD narcotics officer was arrested last Friday on charges he used inside knowledge to run drugs for a Bronx-based cocaine and heroin trafficking ring. Detective James Calderon, a 13-year veteran of the force, was arraigned on drug possession and conspiracy charges. Prosecutors allege that Calderon smuggled a total of eight kilos of cocaine from New York City to Virginia on two trips in 2004 and 2005. Calderon went down after attempting to get an impounded minivan released from police custody. NYPD officers at the 44th Precinct refused to release the vehicle to Calderon, then searched it and found a kilo of heroin inside.

In Scranton, Pennsylvania, a former Scranton police officer was sentenced Tuesday on Oxycontin delivery charges. Then Scranton Police Officer Mark Conway was arrested in March after an informant told police he had bought drugs from Conway on more than one occasion. He pleaded guilty in August and resigned from the force. Now, he will do one month in prison on a three-to-18 month sentence, and then he will be placed on work release. Conway's defense attorney said he wasn't a "drug pusher," but a drug user who occasionally sold drugs to others.
