Accidental.. I would say they sniper(s) was planning on 11 deaths..
Yeah I think it is just a coincidence also, but it is still kind of eerie.
If they were planning on 11 deaths, do you think that 11 could indicate November--11th month...for another major hit? You never know what these nutcases are thinking and planning, but put nothing past them..Plus, there's been another warning issued by the govt re another one..
