Do you think they go after drunk drivers to prevent drinking? The point is to keep them from driving when they are incapable or unwilling to see that they are. People shouldn't be driving while intoxicated. At one point, there are people having a few drinks, still capable of driving safely. At some point, some people having a few drinks crossover to the level of officially drunk. Impaired. Incapable of operating a motor vehicle safely. We've all seen them, staggering, slurred speech, arguing that they aren't, hic, drunk. And many of them drive anyway. Sometimes we can stop some of them by taking their keys, as friends, or calling a cab, and sometimes we can't. Anyone who's had and lost this battle knows what I'm talking about. And some of them kill people. Don't stop them from drinking. Do stop them from driving while intoxicated. I'm not that familiar with Texas' drunk in public law, and this raid may have been gestapo like or heavy handed, I don't know, but drunk driving kills (not 'drunk' like a drink or 2 with no impairment) and it is always preventable. Always.
