Deletion of Walter Ehrich

Comment: The  who is using Wikipedia to attack this living person also recently vandalized the AfD tag http://en.wikipedia.org/w/index.php?title=Walter_Ehrich&diff=prev&oldid=412119695.  If I see any further policy violations on the part of the user I will bring the matter up at AN/I.  This atrocious behavior is not what WP is supposed to be about
