What happens when this aggressive police tactic becomes the rule, rather than the exception? “Broken Doors” is a new investigative podcast series about how no-knock warrants are deployed in the American justice system — and the consequences for communities when accountability is flawed at every level. Hosted by Jenn Abelson and Nicole Dungca.In the first episode of this series, sheriff’s deputies burst through the front door of a man’s home as he slept.

But that wasn’t the worst of it.The next two episodes are out now wherever you get your podcasts. You can email the “Broken Doors” team with any tips or feedback at BrokenDoors@washpost.com
