At least the lack of cocaethylene metabolites shows that Nick didn't actually piss on his daughter but for a second there I thought to myself "oh god, no"

>If I were to guess it was yooooooouuuuu who took cocaine and gave her a golden shower
"Any testing of the the children that would result in drug use according to the children would be because of secondary exposure from some other source."

Note this is before any results came back.
It's a ludicrous amount of coping and seething.
Let's just ignore all the logistics of the test and assume it was a secondary source.
Exhibit A: Contamination via cop
So why were the cops there in the first place? Because of the way you treated your children, and because you're a druggie.
Where did the contamination come from? YOU. Your unlocked safe full of narcotics.
Exhibit B: Aaron
So what was Aaron doing there? Who brought him into the household?
YOU.
Exhibit C: Lab test errors
Infeasible since it's >5000pg/mg, not 600.
That's also not a secondary source.
All the papers (which I have read in full) at most reached about 1500-2000pg/mg regarding heavily contaminated samples, before any decontamination protocols which is standard in any testing facility.
Exhibit D: Environment
Where?
Your house? Why is the air full of cocaine?
Wouldn't the other children have similar levels?

Give him the best scenario and it's still his fault.
