He was a bystander who stuck around and tried to do the right thing. The people charged decided to go to trial and now he’s on the hook to show up and answer stupid questions under oath.
The objective of the defense is likely to have him not show up.
Isn't that the system working as expected? Presumably a more just outcome is more likely because of your colleague's testimony.
I mean...if the correct outcome is rendered and the fact that he stuck around to help and went to court to testify about it is part of the reason why...why would you portray that as something negative?
