I would make no appologies for playing the odds. Clearly most folks are good, including those living in trailer parks, but crime from those with fewer possessions and income is greater than those with more. It may be politically incorrect to profile, but it is quite effective. The goal should be not to put everyone in the same basket, but learning from experience keeps us safe. Prejudice often develops based on real trends, but that does not give one the right to take negative action without evidence that an individual is guilty of something. Once bitten, twice shy.
