One whole barrel of bad apples. One wonders how common this is in the Police depts across the West.

A disgraced ex-police officer testifying against his drug squad colleagues acknowledged Tuesday that he stole drug money, planted evidence and lied on police paperwork too many times to count.

Jeffrey Walker told jurors that the Philadelphia Police Department drug squad targeted white “college-boy … khaki-pants types” who were “easy to intimidate.”

Walker agreed to cooperate last year after being caught in an FBI sting stealing $15,000 from a suspect and planting drugs in his car. He has been in custody for nearly a year and hopes to avoid a life sentence through his testimony.

More than 160 drug convictions have been overturned since Walker pleaded guilty and the others were named in a 26-count indictment. Scores of civil-rights lawsuits are pending over the arrests. Police Commissioner Charles Ramsey has voiced his disgust with the squad’s alleged crimes while continuing his effort to clean out and reform the 7,000-member department.
