Not yet 17, I disobeyed my parents and drove to the police barricades at the far end of Osage Avenue after nightfall, as close as I could get to the bombing – I needed to see it with my own two eyes. The overwhelming memory I carried away with me, though, was olfactory, and not visual: I promise you that nobody within a five-mile radius of West Philadelphia that night will ever quite be able to get the smell of that murder out of their nostrils. It’s 38 years gone by and it feels like yesterday.
