Those lolicon images are not child pornography and are not illegal in the United States. They are not a direct admission of having comitted any crime and do not provide probable cause. Wikimedia isn't going to get handed a warrant for that.
LS is child pornography, is illegal everywhere, and hinting that one downloads it is enough for probable cause.
