I think the best thing to do with this video is to get it shown on forums all over the Internet, particularly parenting forums.
As a loyal JW I would have cringed to see this video being shared with and discussed by 'worldly' people, I definitely wouldn't have felt proud. I don't think I would have even wanted to share it with a study.
As for non-JW's, you can pretty much guarentee that any who see this disturbing stuff will run a mile from any JW trying to convert them.
Contacting the press is unlikely to have much success imo, you need to get it going viral first, then the press might get interested. I would do it in a heartbeat if I wasn't concerned about compromising my anonymity. (My fade isn't going too well and the elders are onto me already). I'm a member of a few parenting communities online and I know that if this video got posted for discussion it would be viewed by potentially thousands of concerned parents. It's best if you're already a member of a forum though so you don't just 'hit-and-run'.
Hopefully someone here has more balls than me and will do this.
I'm thinking mainly about the wizard toy video. Nothing negative needs to be said about it, the GB have done all the work for you . It's clear they never intended this to be seen by non-JW families and will have really shot themselves in the foot if it goes public.
