Sorry, but this is WRONG WRONG WRONG. Why not just arrest people who are in line at the market buying beer? Chances are they are going to drink it and drive later? Some of the people arrested in Irving were at a hotel bar, and were guests there! How is this making the roads ANY safer??
This is stupid, over-reaching, and blantant authority interference with simple everyday acts.
There's no 12-step program for stupid.
