Says here 8 churches in 10 days,So they started with 6. One turned out to be a "white" church. Takes us down to 5.
One was ruled accidental and another was caused by a tree limb/electrical line.
That leaves three due to arson...none of which have yet been linked to racial motivation (churches get robbed and vandalized by common criminals everyday).
Three. Hardly an epidemic. How many "white" churches burned due to arson across the country in the same time period I wonder.
3 confirmed arsons.
