We do have "food deserts" sometimes caused by grocery stores staying away due to security concerns, more common in high crime / low income areas.
...Which is where Walmart is allegedly known to swoop in, because everyone nearby tends to be desperate for a minimum-wage job and a place to buy food regardless of quality. Sort of predatory, but better than nothing I guess.
Wait, why? Not to complain, but it's essentially law that when federal courts have jurisdiction, a civil case may be 'removed' from state court and into federal (district) court upon the defendant's request -- and it seems pretty clear that federal courts have jurisdiction over civil cases arising under the Constitution. I guess the court technically has discretion in some cases, but that's pretty surprising.
