Sean "Diddy" Combs' trial began this morning, with 8 men and 4 women selected to his jury. He's facing federal criminal charges, and a life sentence if found guilty. Both the prosecution and the defense gave their opening statements, and the prosecution called their first witness; an LAPD officer who worked as the Assistant Security Director, and was the responding hotel personnel during the March 5, 2016 caught-on-video assault of Casandra Ventura — the woman who brought the downfall of Diddy and his empire.
