The trial of four former U.S. security contractors in the deaths of Iraqi civilians is just getting underway. The former Blackwater employees allegedly opened fire at a busy Baghdad intersection in 2007. Now, seven years later, prosecutors are sorting out if they can be held criminally responsible. In this week’s legal loop segment, employment attorney Debra Roth joined Tom Temin and Emily Kopp on the Federal Drive. She explained why the case has taken so long to go to trial.
