Don't have TV, but reading articles online as they come up. Keep me up to date (thanks for that so far by the way.)
From what I read from papers in these type of situations, from witness statements and such, there is one of many thing I can't understand here.
If these witnesses are hearing explosions and what sounds like gunfire.... WHY are so many of them going closer to investigate!? They make themselves potential victims for one thing. And also, the cops have enough to deal with. Don't distract them by having to worry about citizens too.... Or heaven forbid they mistake a bystander for a potential threat in the heat of the moment.
Personally if I hear gunfire I'm backing out of that area and preparing in case things get bad despite my best efforts to leave.
