Riot police

So today I was innocently on my way to a work meeting, and I came out of the metro not really paying attention to anything and was confronted with a large group of riot police and what looked like a tank. There didn't seem to be any mass disturbance or anything, they were just hanging out minding their own business, in their riot uniforms, as you do.... Turned out it actually wasn't a tank, only a water canon. They had what appeared to be a bit of a test fire when I was crossing the street (quickly in the other direction), which cleared that confusion up for me. I don't know what they were doing there, and no one else seemed particularly worried about their presence, so I guess it wasn't anything major. Apparently this happens near our office quite often, because we are right next to the Uni, and the students like to have a good riot every now and again. Apparently, it is really annoying when you go outside the office to go to a class and they have just let some tear gas off and you end up crying all the way to class... Annoying! That was the word my fellow teacher used! I think I might find it more that annoying! Anyway, it made for an interesting morning, and a good story! K
