A Constitutional Issue?

In just a few hours the Texas' "No refusal weekend" will come to an end. You may ask just what this is and what it entails. I'll be happy to tell you. You see, any police officer in the Republic can pull you over for suspicion of being hammered behind the wheel and mandate that you have  your blood drawn to test for intoxicants.
OK I get it. We don't want, or need drunks and other intoxicated fools behind the wheel of an automobile. They cause havoc and cost lives. That being said, do we really want just any cop having that much authority? Not in my country. So far we are not citizens of a police state. Heading that way sure, but still a long way off.  There is a trade off living in a free society with legal protections such as "innocent until proven guilty," protection against illegal search and seizure, etc, etc. Do we need to go into what that trade off is?

Again I agree that drunks need to be taken off the road but it is going a bit far; way too far; when any cop has the legal authority to have blood drawn.

I don't like that vato. I don't like that!
