Philadelphia prosecutors are demanding more and better evidence from police -- more witnesses, more documents, more phone and video records, more searches, before filing charges, says the Philadelphia Inquirer. That mandate, imposed by District Attorney Seth Williams when he became the first new district attorney in nearly two decades, is designed to make cases stronger in court.  Statistics show that a greater proportion of cases are advancing to trial.  Williams' policy shift has sown tension between prosecutors and police. Critics say the new system is frustrating at best, and at worst, risks permitting dangerous people to remain free and strike again.
