If Chattanooga wanted to control schools, it shouldn't have abdicated. Better two school systems than the constant bickering. The county's error was in treating the matter as a merger.
"U.S. Supreme Court decisions have said out-of-state retailers cannot be compelled to collect sales taxes by states or local governments unless they have a physical presence."
For all practical purposes as a retailer Amazon will have no physical presence in TN. There is no showroom - no place to look, browse, touch, etc. It is simply a shipping address that could instead be CA, NY, TX, or GA; something pretty much transparent to the buyer. If the consumer chooses to buy from Amazon, it isn't a decision based upon the location of the distribution center; however, that distribution center, wherever located, does put jobs and income in the hands of those living locally. Making the stand to collect sales tax and losing the industry is simply winning the battle and losing the war. Face it; right or wrong, state and local governments make very lucrative tax deals to lure industry for the jobs - for the local economy - simply another variant of peer pressure.
Of course, the connection between events like this and using unmarked cars for traffic enforcement goes ignored. Clearly marked cars intended to be readily recognized deter incidents like this because the public understands that an unmarked car is not the real thing. A high profile vehicle on the other hand is likely a bit too obvious for an impostor. It would be difficult to identify a car with blue lights behind you at night in any case, but light bars on top are far better than hidden lights in the grille or windows. I've always wondered who was driving the cars with virtually black windows, standard plates, and nearly invisible blue lights. And what better means of transportation for a terrorist than an unmarked police car.
