Republican presidential candidate Marco Rubio said the US should be "vigilant" in prosecuting police officers who do a bad job, but he also warned of the danger of demonizing people in law enforcement in the wake of a number of high-profile cases.
The Guardian asked Rubio during an interview on the campaign trail in Iowa if the Justice Department should require police departments nationwide to report on excessive use of force and killings by law enforcement.
Rubio did not call for a federal database of such incidents, but said they are reported "in essence" by the media.
"There's no police incident that exists in this country that's not documented in the press, so it wouldn't be hard to put that together one way or another," he said.
