Rage Against the Machine - Freedom Lyrics Meaning

I think it's about how police
And law enforcement are always hurting and fucking up people of color. The reason I think this is because of the lyric " we'll us a pair of clubs to beat the spades." Also because they say "brother, did u forget your name? Did u lose it on the wall playing tic tac toe? Yo, check the diagonal, 3 brothers gone c'mon, doesn't that make it 3 in row?"
