Russ,
Legally I don't know what he can talk about. There was a big lawsuit with Atena Insurance suing over the cavitat device. They don't want to pay for it's use.
The cavitat will show osteomylitis way before it shows up on a panorex x ray and this means it would take money away from those promoting a sick population. Dentist would also be a fault for poor dentistry.
He did ask that we pray for him. I think the fact that he is not ashamed of the gospel of Jesus Christ is a major factor in his persecution.
But when I email him I will ask him if he's willing to share anything with us.
