On June 13, 1966, Justice Hugo Black joins Justices Clark, Harlan, Stewart, and White in rejecting Ernesto Miranda's appeal.
https://en.wikipedia.org/wiki/Miranda_v._ArizonaThe phrase "Miranda rights" does not enter the language. In this ATL is the decision later overturned? (I say yes).
Do the 1966 elections show such a strong swing to the right (and does the "law and order" issue still carry the day for the next quarter century)? Does the violent crime rate increase as much (1966-1974) as IRL? Personally I'd say No, Yes but not as much, Yes, and George Wallace maybe gets marginally less support, but not much would be different.
