“There’s no way to search for that,” said Neva Coakley, a spokeswoman for the Boston Police Department. “We wouldn’t be able to speak to that because we don’t have data to support it. We don’t distinguish between what type of suspects they are.” In other words, Boston doesn’t track assaults by where they happen—in a taxi, in an Uber, or in someone’s home—so there’s no data to compare reports against Uber drivers versus taxi drivers or limo drivers. That’s true in other cities, too.
