Johnnie Cochran's widow is FURIOUS at former O.J. Simpson prosecutor Chris Darden ... claiming allegations that Johnnie tampered with the infamous bloody glove are pure B.S.
TMZ spoke with famed attorney Shawn Holley -- Cochran's former right hand woman-- who tells us Johnnie's widow Dale Cochran is outraged by Darden's claim ... explaining, "It makes no sense."
Darden recently made the comments while speaking at Pace Law School ... saying, "I think Johnnie tore the lining. There were some additional tears in the lining so that O.J.'s fingers couldn't go all the way up into the glove."
Holley tells TMZ ... if Darden really did believe his insane theory he FAILED in his legal obligation to raise the issue in court ... adding, "to bring it up 17 years later when Johnnie Cochran is dead ... it's just, it's unbelievable. It's maddening."
