Back in ancient times when I was growing up my parents and cousins' parents (next door neighbors) each bought large kits of "Safe and Sane" fireworks. We chose a spot on the farm tens of yards from structures, cleared of vegetation and wandering mammoths and set them off there. We were careful in the handling and lighting, yada yada yada.
Setting off fireworks in a city, in a driveway just 20 or 30 yards from a house, maybe 10 yards from people, 3 or 4 yards from a pick-up, with multiple people doing the lighting and staying a few feet away, that amount of stupidity probably was literally painful for a few people.
