No clue. Sure someone probably had a cell phone and made a call in or something. I mean hell, I was in one lane, he in the other, and we're both blocking traffic and fighting on Bruce B. Downs.
Regardless though, I was just defending myself and my property. There was a variable out there and I had to take it out of the equation.

But yeah...I was a bit lucky. When I got back into my car and drove off, I ended up passing a cop going the opposite direction less than thirty seconds later. :o
