Whites are getting killed in the same numbers. By whites.
By the numbers it is actually pretty close; roughly 80% of murdered blacks murdered by other blacks and roughly 80% of murdered whites murdered by other whites. What's missing is that the actual numbers are so close - roughly 3200 a year whites murdered and roughly 3000 a year blacks murdered. There are approximately 5 times as many whites in the US as their are blacks but the numbers are close to the same. Murder in the US is committed by blacks against blacks at a much higher rate than any other group association.
But you're right that all of it needs to stop. We need to stop the crime tolerance at all levels in all communities. Make examples of all violent offenders so that others will consider the consequences before harming other human beings. We should not lessen the white-on-white crime by pointing the finger at blacks and saying, "but they do it more than we do." But it's not as simple as whites working to stop white murder and ignoring black on black murders while blacks work to stop black on black murder and ignore white on white murder.
Mostly, they have the same societal causes and Americans, regardless of skin color, need to work to deal with those causes. End the war on drugs, hold fathers accountable for caring for their children. Use DNA to identify fathers in each and every case where a mother claims not to know the father - and hold women accountable where it's the other way. Put violent criminals in terrible prisons for very long periods. Community education on the costs of crime: let kids know that if they commit a crime they 're going to prison and they won't be playing basketball.
If we don't have the will to do those things, black and white, the murders will continue. I, for one, am tired of hearing about people being killed regardless of race of victim or killer.
