What would you consider the minimum percentage of deaths for something to be a concern worth protesting? Historians estimate that fewer than 4,000 black people were lynched in the years between 1877 and 1950 [0] -- e.g. about 55 per year, which makes being lynched as an African-American not "statistically relevant" by your standards. Were the protests by African-Americans in that period unnecessary?
