Senator Warren on law enforcement

See her article here. She provides several examples of those that commit crimes and yet the law is either not enforced to punish effectively. Not least of which is the example of Wall Street and the crash it deliberately caused, where not one of the executives of said banks incurred criminal penalties. Warren encourages us to select a candidate and President who will not only suggest new laws but enforce those already on the book. While she doesn't come right out and say it, it's clear which Democratic candidate that would be (Sanders), and which one it wouldn't be (Clinton). Just  follow the campaign money.
