"I'm an older white guy. I'm going to stop, I don't feel threatened," said Jeffrey Butts, a professor at John Jay College of Criminal Justice. "There are people whose rational expectation is that (the stop) puts them in danger. They're going to have different response. It's amazing to me that we haven't confronted that and individual police officers don't think about that. They're just shocked and angered by someone daring to not comply."

Police often say the criminal justice system is a revolving door but Jeffrey Butts of John Jay College of Criminal Justice said his research proves otherwise. "The vast majority of people who are released pretrial do not get arrested again while they are waiting for trial," he said. "About 5%, at most, of people who are arrested and waiting trial and then released get rearrested prior to their trial."
