Yes.  I do believe that soldiers and police before the march were given specific guidelines as usual.  You know that was not the first march.  They have been monitoring marches for as long as you know they know, and in all the marches they monitored their first stance is to stand back and watch until such time as they see some disorder then they may try and solve that.  If it escalates into a fight or a shooting then they know what to do.  Those people have been trained there.  There may be riot policemen there, there may also be policemen and soldiers who constantly sit together and discuss that if this goes beyond our control then it's for the soldiers, because then it means war.  So my answer to you would be confined only to what I know are the standard of preparational procedures and not what happened there because I was not there.
