Thanks for your comment.  Your English is great.  The teargas comment came from a piece that I read in the <a href="http://www.sofiaecho.com/article/natural-gas-teargas-snowballs-and-trouble-over-a-turkish-toilet/id_34012/catid_66" rel="nofollow">Sofia Echo </a> so it could be inaccurate.  Thanks though for your explanation of the rally.  It really helps to clarify what happened today.
