Todd wasn't charged with possessing "CSAM"; he was charged with making a terroristic threat.
In the course of searching his devices specifically for proof that he made said threat [which, FYI, they didn't find], they "just happened" to find a lolicon image [disgusting, but not per se illegal] which, somehow, they imagine was a basis for a new warrant seeking "CSAM".
I know it doesn't, but it
should bother you that your local police and/or Federal agencies can seize a device you own for a specific purpose and then just go poking around looking all through the device until they find something "offensive" and thereby seek out a warrant for some other sort of material. Obviously you don't believe Todd's contention that he didn't go seeking the alleged "CSAM" material. That's fine; because, you know, law enforcement agencies
never plant evidence ever,
nor do they never seek to obtain warrants on flimsy grounds either. /sarcasm
