@r1600turbo and a6m5, Im pretty sure it was plausible. Speeking from my own experience though, I live in SOCAL and I've heard it reported by the news numerous times that in bad neighborhoods I.E. Compton, Watts, Inglewood etc. around times of celebrations like new years and cinco de mayo many people have been hit and killed by falling bullets, yes falling and not stray. This also goes for other people who doubt you could be hit or killed by one.
"Between the years 1985 and 1992, doctors at the King/Drew Medical Center in Los Angeles, California, treated some 118 people for random falling-bullet injuries. Thirty-eight of them died." -Wikipedia
