You are lucky you manage not to get hit by any debris. However this is a sad story as well.. Both party suffering for something that is Govenrment should look about it. A peaceful talk could have eliminated this and no one got hurt. Sadly in event like this Policemen don't have an option but to protect the constitution in which they got hurt as well. Vice-Versa ... This really saddened me every time I see people get hurt for the wrong cause.
