Former U.S. Marshal on the challenges of judicial security

The fatal shooting at a New Jersey federal judge’s house on Sunday is raising questions over the safety of those who serve on the bench. Authorities say men’s rights attorney Roy Den Hollander disguised himself as a FedEx delivery driver before opening fire and killing the 20 year-old son of Judge Esther Salas and wounding her husband.  Den Hollander is also now linked to another murder in California.

Experts say attacks on judges and their families are considered rare. But a U.S. Marshals Service report shows threats against federal court workers are on the rise and cases have quadrupled since 2015. Retired U.S. Marshal John Muffler joins Senior Correspondent Briana Vannozzi to explain.
