I think that the only arrest that will be made is on Shawn becuase this implicates him in my opinion as there was *advertiser censored* also found on his Mom's computer. This makes me think that he downloaded it on his Mom's computer and then transferred it onto the jump drive to have at home. Regardless if it was found in Billie's drawer she may have placed it there and not had a clue what so ever what was on it. I mean it doesn't in my opinion necessarily mean she knew what was on there. She could have placed it in the drawer so he didn't lose it and then it got shuffled around and into the corner.
