I'm aware that it does not trample anyone's rights directly, but keeping track of 'racial tensions' in certain areas strikes me as ripe for abuse if done improperly.
But not monitoring that situation would be a gross failure of Government's duty to protect the people. If you don't bother to watch this sort of thing you end up with things spiralling out of control, and before you know what's hit you, you get riots.
At the same time I think a black familiy is entitled to know if the community they're about to move to has a serious problem with racially motivated crimes.
