I could not see any guns drawn - but the locals LE were obviously HIGHLY concerned and actively searching.
If those weapons WERE drawn, then they had firmly established a THREAT CONDITION existed far prior to the shooting (at least two minutes).
Inexcusable - couple that with the revelation that the SS Counter Sniper Team(s) had only been approved the PRIOR DAY - this really does have the imprimatur of a US GOVERNMENT black flag op.
