You’re right that it’s a show trial. And like other show trials like this they’ll be overcharged with no lesser alternatives. It all depends on whether their attempted arrest was legal as determined by the jury. If not they’ll be doing significant jail time.
As Lavrentiy Beria noted. "Show me the man and I'll show you the crime."
There is a quite good chance that the jury's verdict will be entirely the consequence of who sits on the jury, and not a consequence of what is actually true or what the law actually says.
When I was young and naive, I thought juries usually got it right. Then I saw countless examples of where juries got it absolutely wrong. I have no faith in juries, especially ones empaneled for a seriously hot potato trial.
This one has the potential to be another OJ Simpson trial, with the entire country taking up sides.
