Exciting drug run

By "drug run", what *I* mean is a 3-block walk to Walgreens. Not sure that's what everyone else meant by it tonight... During that short walk, I counted 5 patrol cars, 1 police van, 3 unmarked police cars, and 2 police bicycles. And I probably missed some. Luckily, I seem to have ventured on my errand *after* the main part of the fuss was done, as all those police seemed quite calm. Something about "shots fired", but I don't know any details...
