Aside from That Mrs. Lincoln, How Was the Play?

I noticed quite a few police cars with sirens on my way home from work yesterday. I assumed it was because yesterday was Free Ice Cream Day at Ben and Jerry's, and they couldn't contain their joy. But no such luck. I was about two blocks from the Ninja Fortress and I asked someone who apparently saw what transpired.Guy: There was a gunfight, right here. [points to where we're standing]
