I applaud those who went out to hassle the petty tyrants. Honestly those who take part in those road blocks are some of the most despicable people in the world. Seriously, anyone who would willfully violate their fellow citizens like that are no better than the TSA.

Because the idea that you can catch a drunk driver by harassing the rest of the populace totally self-justifies. Never mind that you will violate many more than you will actually catch. Never mind the law exists to protect the innocent from abuse.
