Probably why two windows were broken out, one for concert one for tanks. Could gunfire in different directions cause one to think two different shooters?
“Could gunfire in different directions cause one to think two different shooters?”
Definitely - especially taking into account the entirely different echo patterns. I bet the experts will be able to tell which window he was shooting out of and when.
The one window opened up to other tall buildings (like where the cabbie captured what I believe are very loud echoes).
The other window faced open space - so less echoes.
