well if you're a normal person you know of course the saftey of a child is way more important then a grow, which can be fixed within months, whereas if things keep up this way, at the very least that kid could grow up with problems, be abusive himself and all that, or it could escelate to andrea yates type shit. if i was you, i'd either scrap my grow, or find a person to take it on for a few weeks first, then call the cops... there's no reason you should go to jail just because you are looking out for the kids and the parents get mad at you and retaliate... because you will go to jail alot longer for your grow then they will for the abuse... i wouldn't just sit by and let it keep going on, i'd do something about it asap... if you don't want to scrap your grow for it, if you have a crimestoppers program in your area... i would suggest doing your best to disguise it as good as possible (of course if these neighbors know about this grow, you'll be screwed) and call crime stoppers and report anonymously... don't tell crime stoppers anything that would give you away.. just tell them you know the kids are being abused, and you'd like them to go check it out, don't give them details of it, or any of that... because the more details you give, the more it could single people out, if you just report abuse and they go looking into it, then all that he parents will know is that someone reported them for abuse, not specifics, which could be just about anyone, where as if you give details, (especially if the kids are hardly ever seen) they could single out everyone that could of possibly seen these details, and narrow it down from there...
