In Texas we have something called the Texas Alcoholic Beverage Commission (TABC) which is the agency tasked with "overseeing" liquor sales, distribution, enforcement, and God knows what else. For the most part it seems a monumental waste of money. Texas is feeling the pinch of the economy now and state coffers are running low and one would think it would be time to think about some trimming. The TABC is an agency that should certainly be looked at.
Now there are those employed by this agency who believe themselves to be police officers and technically; legally, this is so. However their main job is to try to entrap store clerks into selling liquor to underage drinkers. Also they keep "tabs" on bartenders. We all know there are bad apples who will intentionally serve or sale to anyone but for the most part people in the business obey the law. To have an entire "police force" running around investigating such nonsense is just going a bit far. The local PD or Sheriff can handle this with ease.
I would be embarrassed to be a TABC investigator. I certainly would not think myself a real cop. Not really even on the level of the local rent a cop. I would submit that these folk need to "get a job."
