What Martin Luther King led American blacks to do was to end white terror, which they achieved by daring to be beaten and arrested and filling the jails.

It makes me sad that this white terror has substantially returned — mainly from thugs, but also (with "stand your ground" laws) from any non-black with a gun.

Compare the advice that black teenagers receive today about how not to be shot by thugs with the 1960s advice described in the first reference above.

Even worse, since the 1960s the US has come to impose permanent punishment on people convicted of a crime, or even (in some cases) accused of one. It is hard to have a mass movement of idealistic young people ready to get arrested and pack the jails when they know they will be excluded from education or employment for life as a result.
