US Flags on Brooklyn Bridge Replaced With Mysterious White “Surrender” Flags

Two mysterious large white flags were flying over the Brooklyn Bridge in New York City this morning in place of the US flags New York City police is investigating how this happened, why and who did it.
ABC News reports:
“This has nothing to do with a film shoot,” said Dean McCann, Executive Director of NYC’s Mayor’s Office of Film, Theatre and Broadcasting.
The white flags are in the same place where American flags typically fly atop the bridge.
It was unclear why they were there and who put them there, authorities said.
The City of New York is loitered by government spy cameras to “protect us” in the event of witness-less crimes. It is a clear violation of the 4th amendment and citizen privacy rights. So where is this footage, or did it go by way of the IRS emails?
