I'm sorry, I'm just laughing about the jokes about Henry planting evidence, picturing him yoinking his own hairs out, or like hairs from one of his pets falling off his clothes into the evidence or something, oh no (that's what would happen if I were Henry). I can just hear the discussion in the trial regarding hairs from a pet, what kind of hair, etc. Oh dear
I think the defense brought up the hairs that Henry found in order to support their argument for needing to have had access to witness evidence collection etc rather than having to rely on reports as provided to them. Because the reports provided to them obviously would not have contained any info about these 17 hairs, etc. (I didn't know it was 17 either, though, I thought it was just a couple additional ones that were listed in the evidence, I was surprised to hear 7 or 17 or whatever it was. Oh I guess that's their point, that it wasn't mentioned in the evidence reports? Well, I wonder what info will come out about these hairs. I do wonder whose they are.)
