Riots in Jerusalem

You may have seen on the news that there has been some violence in Jerusalem yesterday.  Apparently an Arab boy was found murdered and some are claiming it was done as payback for the three Jewish boys who were kidnapped and murdered.  What the truth is, I don't think anyone really knows right now, but it caused some rioting in the city.  None of it was in the area I live in or work in, and the only clue I had to what was going on, was the fact that the train I take to the post office every day was not running regularly.  I didn't know why, and such is not abnormal enough here in Jerusalem for me to even question it.  I didn't find out until I got home last night and was playing some games with friends, that apparently people were tearing apart the train stops in the area near where the Hebrew University was located as violent protests to what is going on.
