32 years in the Army taught me that first reports are almost always wrong. An Ariana Grande concert is a tempting target, in that she symbolizes much that Islamists hate, and it is a large soft target.
However a concert venue has a lot of electrical equipment that can go bang or explode.
Too soon to rule anything out or speculate.
Thanks for your perspective on this.
Evidently, in the foyer/ticket area there was an explosion of some sort, and there were dead people in that vicinity.
As you state, there are things that go bang in places, and it’s not impossible that it was some form of equipment.
I tend to doubt that would cause fatalities though.
We see as it plays out.
