This one was motivated by pure hatred and bigotry against Blacks and Jews. That guy has a long history of bigotry that law enforcement agencies were on the lookout for a long time.
I have to say that anti-Black and anti-Semitic hatred are still prevalent today.
My heart goes out to the family of the security guard, Stephen T. Johns, who was killed today. May he rests in peace.
As for this racist bigot, I hope he gets the maximum punishment available.
