A Philadelphia judge Thursday sentenced a former city cop to jail rather than probation because he said the defendant lacked remorse for the serious offenses he had been convicted of and because he undermined the criminal justice system.Common Pleas Judge Earl W. Trent sentenced Aleksande Shwarz, to 1 to 2 years in jail and two years of reporting probation for roughing up a U-Haul store manager and then lying to make it look like the manager had assaulted him. The sentencing terms indicate that he could be eligible for patrol after nine months. Shwarz, 56, who had been on the force for 21 years at the time of his arrest, declined to speak during the hearing. His wife broke down upon hearing the sentence and had to be helped from the courtroom.
