You DID notice that this is from San Francisco, didn't you? There is an abundance of IQ problems there. If you don't believe me, check out the guy they elected as mayor.
If you average Redding & Ontario, you come out about 100 miles south of San Francisco...but the thought is the same.
Just as a bit of background, Redding used to be, as of a decade or so ago, a 'dumping ground' for paroled perverts.
