"Denial..."
Yeah, way to avoid the subject.
The painful reality is that checkpoints treat ALL citizens in line as though they have committed a crime (otherwise, why stop them from their travels?) until the citizen proves their worthiness to pass.
So what am I denying exactly?
That applied in certain conditions will produce arrests of people with warrants outstanding, weapons and drugs.
You won't produce much in the suburbs but do it in high crime areas and the results are much different.
