When you advise a client to perjure, you are knowingly advising them to break the law. There's no room for good faith.
When you make a good-faith effort to devise a plan of action that, in your estimation, stays within the law, you're doing your job.
So, in order to convict on the same basis as your spurious perjury example, you add a new level of proof, a new element of the crime -- you have to prove beyond a reasonable doubt that these attorneys were NOT making a good-faith effort to stay within the law.
I'm sure you'll say it's "obvious" they weren't, as your bigotry only allows you to see things in one exceedingly narrow way, but fortunately, the justice system is a bit more dispassionate and deliberate.
My prediction: we will see no prosecutions, because no prosecutor will think he/she can get a conviction on the fact pattern. If there's anything at all to be done, it will be on some low-fruit ancillary thing falling far short of the TORTURE!!!!!!!!!!!!!! convictions you want.
