As President Trump's crime crackdown got underway in Washington, D.C., in August, federal agents and police spotted a man tugging at his backpack inside a Trader Joe's, searched it and recovered two firearms. But federal prosecutors were forced to dismiss the charges after video surveillance revealed the search lacked probable cause and was unlawful.
In a subsequent legal opinion, a federal magistrate judge said the errors were part of a broader pattern of "unprecedented" prosecutorial missteps, resulting in a 21% dismissal rate of the government's criminal complaints over eight weeks, compared to a mere 0.5% dismissal rate over the prior 10 years.
