Aaron Babbitt really should answer questions about this. Did he consent to the cremation or not? If not, why haven’t we already heard him object? If Ashli’s ashes were provided to Aaron for her memorial service, then he must have started communicating with the government at some point.
His muted and rather slow response (to a whole slew of issues having to do with her death) is puzzling. Though it could be he's saying and doing things we just never hear about, thanks to the corrupt media. Still, I'd be shouting non-stop from the rooftops.
Aaron was informed about the personal hell on earth the government would put him through if he started to make waves.
