If it was Oscar Grant in 2009, SF Bart cop Johannes Mehserle was convicted of involuntary manslaughter and served 11 months for mistaking his pistol for a Taser.
I have known the Mesherle clan for 50+ years - two brothers and a sister (J's father, uncle & aunt). To this day we all spend time together. All of us went to the same school, hung out together and resided down the street from one another.
There was never any denial among the entire family as to the circumstances and or the trial outcome. Johannes's father gets very incensed when Grant's family speaks of coming back for a second settlement from TPTB.
