The very first "gun-control" laws were indeed against African Americans.  1640's on we see a series of them.  The Virginia slave code of 1680 said, “It shall not be lawfull for any negroe or other slave to carry or arme himselfe with any club, staffe, gunn, sword or any other weapon of defence or offence."

And, THANK GOD their lawyers pushed for a jury trial.  The Feds screwed themselves all over on this one and they knew it.
