This is actually quite an interesting case study for jury selection / vetting. The motive clearly relates to political views about the healthcare industry that affect every single American other than extreme outliers. It's therefore pretty impossible to select a jury that can be entirely neutral. Because no matter how politically unengaged they are, it still affects them.
Arguably, the most neutral person would be someone who hasn't interacted much with healthcare as a citizen. But healthcare issues in America start straight away from birth, because the process of birth itself is a healthcare matter for both mother and child, and there's no opting out from being born. That's only not the case if you're foreign born or from a very wealthy background, but you can't have a jury comprised of just them because that's not representative of the American public.
I wouldn't be surprised if this drags on for a long time before any trial even starts. In fact, I'd be suspicious if it doesn't.
Many young, healthy people haven't had to deal with it much, but this is also the demographic highly engaged on social media and probably very sympathetic to him.
