New York Court of Appeals
The New York Court of Appeals, in The People v. James Kent, rules that merely viewing child pornography (or having a cache of it, as on a cell phone), despite its offensiveness, is not in itself illegal in the state, so long as one is not aware of the cache or did not download the images ono a drive in order to view them; state legislators have stated they will work to close those loopholes through formulation of legislation. Distribution, production, and purposeful possession would still be illegal.
