Why would ANY parent of children under 18 be STUPID enough to get involved in the drug trade, even legally selling the paraphernalia?
Why would any government worshipper suppose that terrorizing young children is justified by the activities of one or both the parents?
Remember: if you are EVER even ACCUSED of any illegal activity, the same can be done to your children, or your nephews and nieces, or your grandchildren, if they are with you.
They know the risk going in when they operate on the fringes. The mindset of people today is even if they break the laws ultimately they will get a slap on the hands at worst....which is generally quite true.
As for their children....well it's apparent were they serious about their welfare they would not be involved with such a "business" in the first place.
