From Gallup today:

Which would you prefer to see in your local area -- [ROTATED: a larger police presence than currently exists, no change, (or) a smaller police presence than currently exists]?



The report notes:

In general, though, majorities of these major groups profess wanting "no change" in the police presence in their local community. However, blacks are the least likely to say this at 51%, compared with Hispanics at 59% and whites at 74%. Only small percentages of any group say they want a smaller police presence than currently exists.

I suspect that the difference is not race as such but rather the likelihood of living in a high crime area.  If Gallup, or any poll, asks this question again, it would be interesting to record precisely where each respondent lives and then cross-tab that with actual local crime rate.
