So Eric Holder is saying we should, in effect, repeal "stand your ground" laws.
He believes they are racist in nature.
"Stand your ground" is a purely defensive mode.
It implies resisting attack.
If it is a racist tactic, it must be directed at a certain race.
We can guess the race Holder is concerned with.
All this implies that the majority of those attacks are being perpetrated by a certain race.
Eric Holder is saying that blacks are the primary assailants in this country.
