"Police tape could be seen on Sunday morning near a pile of shoes outside the bar where the gunfire erupted."
The excellent Dutch researcher Ole Demmegard has said that photos of shoes are the calling card of false flag operations, many times at shooting,bombings etc the news shows pairs of shoes.
You can see Ole's vids on YT, just search for Ole Demmegard shoes or watch his great interviews with Alfred Lambremont Webre.
