Funny you should bring up Gary Halbert and all since he's a ex-convict as well.

Prison or some connection to it may very well get you out of the copywriting jailhouse.

I just came across another story about a killer mutant by the name of Hitler.

Turns out he wrote Mein Crap while in prison but here's the kicker it seems his power and influence in the outside world grew while he was physically in prison. Experts say without him GOING TO JAIL he would've FAILED.

On the other hand take a guy like Nelson Mandela his power and influence grew (thank goodness) while in jail.

Gary Halbert wrote the Boron letters while in jail.

Rappers go to jail all the time then sell million dollar albums.

How about putting together the Jailhouse Copywriting Bootcamp?
