... why should I be required to eloquently reply...?
It is not required to be eloquent. What is required is to be respectful. To participate on this community, one is required to follow the rules set forth by is owners and to which @AndreaMoore (thier official representative) earlier provided a link.
As for the topic at hand, no need to wonder about the justification. The article Rob provided contains a link to the affidavit for the search warrant which enumerates the probable cause resulting in the warrant's issuance. It also makes clear the Affiant's intent to search her computing devices to develop the requisite evidence (or in your vernacular, "non-repudiation").
AFAIK, no charges have been issued, so I am not yet able to speculate how easily either party may prevail.
