The privacy invasion was vast when FBI agents drilled and pried their way into 1,400 safe-deposit boxes at the U.S. Private Vaults store in Beverly Hills.

They rummaged through personal belongings of a jazz saxophone player, an interior designer, a retired doctor, a flooring contractor, two Century City lawyers and hundreds of others.

Agents took photos and videos of pay stubs, password lists, credit cards, a prenuptial agreement, immigration and vaccination records, bank statements, heirlooms and a will, court records show. In one box, agents found cremated human remains.

Eighteen months later, newly unsealed court documents show that the FBI and U.S. attorney’s office in Los Angeles got their warrant for that raid by misleading the judge who approved it.
