Agreed, LM has already gotten plenty of publicity to share his “message,” and he would get even more during (but not at) trial.I wonder if he knew that before he committed his crimes and I wonder if he knows it now.
What I envision, though, is that his supporters will be outside the Criminal Courts, in fairly high numbers (enough to make the press show up and interview many of them). They'll have signs and give many interviews/speeches. So, the issue *will* get publicity at trial - just not in the courtroom (although if Luigi takes the stand, a lot will come in - they cannot deny him his rights at the trial, either, it just won't be televised).
Even if he takes the stand, the rules of evidence still apply. There very well could be testimony and evidence related to his medical problems/experience if relevant, but he’s not going to be able to sit there and rail against the healthcare industry for 15 minutes.
