Some things that come to mind...
He's been lurking around town for a couple of weeks now. has he learned anything about the actual crime scene? I'd be interested if he actually knows anything about what happened there that we don't.
But I won't be surprised if he avoids specifics and gives something like his usual presentation with a dash of horrorcore.
Given his mention of dabbling, I'd be interested to hear him talk about the difference between kids that might say have some CDs with occult references or material in their collections and kids that are actually interested in occult practice or are listening to this sort of music 24x7. Also, some of this material is humorous and should not be taken seriously. Mar's School House Glock complete with the badly photoshoped gun on the cover just made me laugh out loud. Going back to my youth for example, Black Sabbath were never seriously interested in the occult, they took the name from a horror movie. By comparison Led Zeppelin, and in particular Jimmy Page, was in the deep end of the occult pool.
Here we are dealing with some material that despite the bad rhyming and low production values, does in fact contain some deeper occult teachings. Does he know anything more beyond the fact that an upside down cross or pentagram could be satanic? I've said it before, SickTanick's recordings are very possibly protected religious speech. Does Rimer recognize that the law actually protects this sort of expression?
I'd also be interested in any statements he makes about the prevalence of Satanic and occult practices among American youth.
