An incident involving a number of "Blue Lives Matter" flags showing up at an African-American Day parade in Rockland has sparked a war of words between County Executive Ed Day and Nyack Mayor Jen White.

White says she's still in a state of shock after being inundated with negative attacks on social media and even death threats after she wrote a Facebook post that some people now believe was critical of law enforcement.

White's post came after the African-American Day Parade in Nyack, specifically criticizing the behavior of several unlicensed vendors who carried large American flags with a blue stripe meant to symbolize the pro-police movement Blue Lives Matter.

"What they were doing was using a police symbol to threaten and engage nice people and families," White said. "They were trying to make it something awful."

She says she took to Facebook to voice her opposition to the vendors not because they had Blue Lives Matter flags, but because she thought they were taunting parade goers.

"There were no issues, no one said anything," said County Executive Day. "No one in the crowd took objections."

Day was with White at the parade and insists that it was the mayor who was out of line, not the vendors.

After White posted her Facebook remarks, Day followed suit, blasting the mayor by calling her story nonsensical and vehemently defending police and the purpose behind the Blue Lives Matter flag. Day denounces any death threats White may have received, but says he believes the scandal is of her own making.

The Rockland County Patrolmen's Benevolent Association has blasted White over her comments. After receiving so many negative comments, the mayor made her public Facebook page private.
