Explanation: The issue of making lynching an exceptional crime (rather than 'just' murder) subject to Federal investigation (and not local 'good old boys' covering it up) was a major issue in the early 1900s, with two attempts by Congress to pass anti-lynching bills, one in the 1920s and one in the 1930s. Both failed due to opposition from Senators from Southern states, predictably.

Notably, President Calvin Coolidge supported the anti-lynching bill in the 1920s despite generally having a very... restricted view of Federal power.

Symbolically, an anti-lynching bill was finally passed... in 2022, long after the most intense period of lynching had ended.
