Juws are split on the political platform. Mainly due to what sect they belong to. One party does not control the Juws vote. Let me break it down for you a little, those that find Israel a giant asshole in the middle east, tend to vote Democratic. Those that find Israel does nothing wrong and is doing right tend to vote Republican. That is not an totally accurate picture, but it depends on what part of the country you are talking about.
Whites are killed a lot more common then people think, the difference is usually it is someone they know. Blacks and Hispanic are more often killed by strangers then by someone they know.
However, a black or Hispanic person is more likely to be killed by a cop, then a white person is. Are you going off law enforcement statistics? Cause if you are, then that data is not accurate as most departments don't keep data.
