We could start a thread, talk to the mods, try to get it stickied.
Not about finding them once their gone, not about GPS for after they are lost, but about the proactive strategies that can be enacted to keep them from disappearing in the first place. National registries that actually work, pushing for registration of child murderers, writing to politicians, speaking out on YouTube.
With the talent and intellect on this site, if everyone gave 5 minutes a day, we could find the strategies and resources to drastically lower the numbers. But we need dedication, and we need to bring this into the light. Off of prime time cable news and into people's living rooms. Constant reminders that it could be anyone's child are the only way to get everyone on the same page about the hell this country inflicts on it's youngest and most vulnerable.
There, all done. Better now.
