IT WAS LATE SATURDAY, about 9 p.m., when James Hall double-parked in front of his home in West Philly. He had just gotten back from a shopping trip with his two daughters, his fiancee, Lakisha Robinson, and Robinson's daughter, Aniyah Curry. The group was getting ready to go back out, Robinson said yesterday, so Hall left the car's hazard lights on as he ran inside to grab something.
