. . . cannot suffice as probable cause to believe defendant was in possession of child pornography"---at least when there's no suggestion that those photographs were lewd or lascivious.
And neither can allegations of child molestation alone provide probable cause to search a suspect's computer for child pornography.
And neither can boilerplate recitations about the assumed proclivities of pornographers and child molesters.
So says E.D. Calif.

The warrant was tainted by numerous Franks violations, and their excision left an already questionable affidavit wanting.
