A barrier of sand-filled dump trucks were parked outside Trump Tower in NYC back in 2016 before Donald Trump was elected President.
In an update halfway through election day 2020, NYPD Chief Terence Monahan said there were "no major incidents to report across the city".
"And we do not expect any as the day goes on," he said.
Monahan said officers had been posted at every polling location since before 6am.
"As the night goes on, we will continue to have thousands of additional cops at the ready," he said.
"My message to anyone that wants to cause violence and destruction is don't even try it, we know who you are and you will be arrested.
"For anyone who plans to peacefully protest in the coming days, we are here for you. But we need your help too. Let those who are trying to cause chaos know they are not welcome. Don't let them steal your message, separate from those agitators and we will deal with them."
