I personally don't feel like it's necessary to have proof they were doing drugs that evening. It seems to be a rather rampant belief that the place was known to be a flop house. If this information was ONLY coming from SM, I wouldn't automatically believe it. However when you combine this "rumor" from many different people on SM, plus you add TF and RF's criminal history, plus the unwillingness of TG to simply let LE search the house without a warrant when they were trying to find HER daughter, plus JR now claiming he was there smoking meth all day...well...if it looks like a duck, walks like a duck, and quacks like a duck...
Do I know there is some slim chance that they were NOT partaking in drugs? Sure. That said, I don't have to base my opinion on "beyond a shadow of a doubt" logic, because I'm not on the jury. I am simply coming to my own conclusion based on what I've read, seen and heard.
Also, I don't feel it's necessary to prove there were drugs there that particular night to make my point. Out of this group of adults that were there that night, I've personally seen the criminal records of FOUR. TG, RF, JR and a woman whose name was just posted on the court docs today. Every single one of them have drug convictions and/or felonies. Heck, RF was just recently arrested for a burglary ring?
Whether she believed JR could/would do this to her daughter or not, she put that poor child in danger.
Typically, I'd find it in my heart to feel sympathy for her. Maybe, just maybe, I've had a quick moment or two where I have. But I have to say, it would sure go a long long way if she'd just come out and say something along the lines of "I never should have trusted him. I never should have let people like that into my home. I should have protected her."... ANYTHING to take even the smallest amount of responsibility.
For now, I'm really on the fence about her level of involvement. The whole "I won't do bad anymore. They've got Bella." comment leads me to believe that at least early on she believed Bella to have been taken as a direct result of something she'd done. So for now, my theory (and it's just that- a theory) is that she angered Justin over something and that something is IMHO, drugs, and she intentionally has not been forthcoming with that information to the police.
I pray that JR is punished to the fullest extent of the law. I also pray that everyone else who has ANY culpability whatsoever is as well.
