Jury duty question

[MH1]

(if not allowed to ask about this here let me know and I will delete)

Question: if a post is alerted on and goes to a jury, can the poster still edit the post? Would the juror be able to see that?

Reason for asking: I've been away for quite awhile, and just got my first jury call after coming back. The post that I read clearly (to me) didn't break the rule. I had a hard time answering the question about intent because I never want to assume bad intent. But jeez, the post wasn't even close (to me). So that got me wondering, is it possible the post was edited to change it that much between when the alert was sent and I saw it?
