Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Porcupine quills are barbed and hard to remove?

Yes. A construction reference states directly that porcupine quills are barbed and painfully difficult to remove from flesh. Other sources corroborate the barbed structure and the difficulty of pulling quills out, though less completely.
