PHILADELPHIA (AP) — The racketeering case against the reputed boss of the Philadelphia mob and six co-defendants is based on half-truths and fabrications from cooperating witnesses, a defense attorney said in opening statements Thursday at the federal trial.

The case mostly involves illegal gambling and loansharking in Pennsylvania and New Jersey, and there’s little violence alleged, other than threats picked up on FBI wiretaps. Joseph “Uncle Joe” Ligambi, the 73-year-old alleged leader of Philadelphia’s La Cosa Nostra, and several co-defendants have pleaded not guilty and plan to fight the charges during the trial, which is expected to last two to three months.
