Another thing to consider is that it's a big section with a lot of people. I think the supporters area holds something like 1200 seats maybe? Also, I had no idea there was a smoke bomb until I saw the photos after the match. I was in 237 in the second row, right on the aisle with 236. That's pretty much where I always sit, the smoke was somewhere behind me, and I didn't even see it. Sure, the people in the row right next to it *may* have seen who did it, but to say the whole supporters area needs to police itself better just seems like it can't realistically be done.
