Honestly I don't know the guy but I've come across several of his patients who were looking for someone to continue his expert high dose management plans.but was he bad enough to lose his medical license? couldn't an argument be made that we need to have some docs willing to take care of these refugees? It sounds like the dea admin personally got involved in his case, and admin with no medical background.
I don't think there should be any argument that there needs to be docs willing to take care of someone else's mess without any impunity.
If someone can so easily ramp things up, then they should be responsible for ramping things down or providing sensible exit strategies for all parties.
