Police Activity

So today I was taking the bus to work and we cross the railroad tracks and a police car is there directing traffic to other streets off the main one we were on. The police let the bus go through I imagine because vehicles like buses and semi-trucks can't go down any of the other nearby streets. As we went down this street towards my work every intersection had police cars, SUVs, and even a squadroll, with officers suited up with bulletproof vests. I looked down one block and there was a large truck with a satellite dish on the top, although it didn't appear to be a news truck, more like a police vehicle. My stop was the one after the last blocked off street, my work was only a few blocks away from where all this was going on.

So I walked into work a few minutes late (with all this going on the bus was late, so I was late). So I say to my boss 'whats going on down here?'. He didn't know anything about it. I had to work until 9:30, and figured when I'd get home I'd see something about it on the Trib website or on the news or something. But nothing. I can't find a thing about what was going on. So, something may or may not have been going on, I can't tell.
