How have courts dealt with allegations of knowing possession or control of child pornography?

Other cases where knowing possession or control were found are in accord with the examples discussed in Tecklenburg. (See People v. Mahoney (2013) 220 Cal.App.4th 781, 793 [the defendant conducted Internet searches for child pornography; accessed pornographic Web sites on three different computers; enlarged thumbnail images; and partially downloaded and then deleted videos]; People v. Luera (2001) 86 Cal.App.4th 513, 523 [knowing possession found where the defendant purposefully downloaded images and kept them on his hard drive].)
