2014 was the year that the police spent in the doghouse, what with the Michael Brown killing, the Eric Garner death, and a few other well publicized incidents. But the only police shooting which was obviously an actual murder was the killing of Walter Scott by North Charleston police officer Michael Slager.
Now, after a lot of of hate crimes which were not quite as advertised, or even hoaxes, we have an actual hate crime. Again, it took place in Charleston.
The odds of such happening in the same state are .02 x .02, or .004, meaning, four chances in a thousand. The odds of it happening in the same metropolitan area are even lower.
It's probably just coincidence. But it's quite a coincidence.
