    I listened to this today after listening to Best Case Worst Case with Jim Clemente and Francey Hakes about the murder of Ahmeud Arbery. I’m glad I was out on the run, so many tears! What broken hearts and hurt families! These episodes with Jeff Rinek showcase who much the family serves with the LEO. The fallout is heartbreaking. I’m glad Mr. Rinek made his way back from the edge and has the courage to talk about it! God bless you all!
