I would not defend racism, but, Donuel says: You see the children sentenced to death are 66% black while only 1 in 4 Americans are black. This is a fair measure of American racism.
Might the 66% be a fair and accurate figure.
I am not claiming that the black populace are any more pre-disposed to crime (that would be racist) But is it possible that they are more deprived, more likely to live in a ghetto culture where gang membership is prevalent, more likely to be living in poverty and pressured into crime?
Any of these would give a reason for a greater percentage of prosecution without that percentage actually being racist.

Claims of racism are easily made, but very difficult to refute without access to a lot more information than is provided in those very sparse statistics.
It is also very difficult to put a counter view without risking being branded a racist.

I hope I have put this point plainly without offering offence to anyone.

Cheers
Nigel
