If the other driver were driving so fast, how was Flemming right behind him at a stoplight so long after the other driver passed him?
If Flemming had started a fistfight, his wife would probably have been there telling everybody that she didn't know why she married that jackass.
However, now that he's dead, her story is going to be that he weren't doing nothing wrong before he died. Imaginative twist, getting a lawyer to deliver that message instead of doing it herself.
(none of this should be taken as excusing the defendant, but let's just say I don't feel deprived by the fact that I never got to meet the decedent and his wife)
