Biden questioned on his support of the 1994 Crime Bill
Angelica Politarhos, a Republican voter from Garnett Valley, Pennsylvania, asked Biden about his view now on the 1994 Crime Bill.
"Things have changed drastically," the former vice president said. "That crime bill, when we voted, the black caucus voted for it, every black mayor supported it across the board."
When Stephanopoulos asked Biden if it was a mistake to support the bill, he said the mistake occurred at the state level.
"The mistake came in terms of what the states did locally," he said. "What we did federally, we said it was -- you remember, George, it was all about the same time for the same crime."
Stephanopoulos also asked Biden about previously saying that more police meant less crime. Biden said that only works if those police officers were doing community policing.
"We had community policing from the mid '90s on until -- until (George W.) Bush got elected, what happened? Violent crime actually went down," Biden said.
"The cops didn't like it," he added. "They didn't like the community policing because you had to have two people in a vehicle. They had to get out of their cars."
Biden went on to call for de-escalation training for police. "So instead of anybody coming at you and the first thing you do is shoot to kill, you shoot them in the leg," he said.
He also called for psychologists to accompany police officers on calls where mental health is a factor.
