The only raids that the administration and Kerlikowske were ever talking about putting an end to were for situations where state law was in disagreement with federal law, most notably "“federal resources should not be used to circumvent state laws.”
What raids of MJ facilites that the DEA has conducted since the public stating of the non-interference policy were only done when they were able to dig up offenses that also violated state law as well as federal law. This still leaves lots of loopholes for the DEA to pounce when state law has not been strictly adhered to as well. The most common one is selling MJ for profit, since this is still illegal to do under Ca. law.
It is still illegal to cultivate marijuana in California (unless you are a medical marijuana patient, or a primary caregiver). Especially growing MJ on federal land.
Although Kerlikowske's statement is disappointing, it is to be expected, and there are no inconsistencies or lies in regards to previous statements at all.
