Expect nothing but chirping crickets on this one from BigBrotherNannyState2nd. I no of no statistical evidence whatsoever that has ever been produced that shows that the same number of LEO's routine patrol work is any less effective than performing unconstitutional stoppages of innocent motorists.

Sobriety Checkpoints
Sobriety checkpoints reduce alcohol-related traffic fatalities by 20 percent on average according to a 2002 study by Centers for Disease Control and Prevention (CDC) scientists published in the “Traffic Injury Prevention” journal. Several studies in the 1990s found that sobriety checkpoints save lives when they are conducted frequently and are highly publicized. These studies, which were conducted in both urban and rural areas, showed that the checkpoints led to a decrease of between 18 percent and 24 percent in alcohol-related traffic fatalities, injuries and property damage.
