Is there any other shooters other than ER who weren't glowniggers undercover?

I swear every other mass shooter is likely a glownigger in disguised and ER and Klebold and Harris is the only ones guaranteed to be a legit mass shooter since he did it in CA and Klebold and Harris made multiple tapes proving they are 99% likely legit, every other mass shooting was a glownigger undercover.
