Despite your use of a question mark, this sentence fragment is not a question, and I have no clue what you might have intended to ask.
"Alot" (or "ALOT") isn't a word, and what you have described happens rarely or never.
This is really confusing. From a strict grammatical reading, all of the pronouns in these sentences refer to the prosecutor, but that doesn't appear to be what you intended. Also, "exculpatory" refers to evidence that has is or may be beneficial to the defendant. Exculpatory evidence most certainly would not "push the entire case in [the prosecutor's] favor." Also, it is quite rare for a trial to take "months."
I have no idea what "lose low key" might mean, but this is about the point where the defense attorney would grab the defendant and tell him to stop talking and the judge would tell the defendant to sit down and be quiet.
Of course not.
What a strange and apparently silly question.
Juries don't explain their verdicts. However, if we're going to live in a fantasy world where a defendant can just get up in the middle of a trial and give a speech, then the jury should probably inform the sentient worm that is acting as a bailiff that they'd like to perform an interpretive dance routine.
That would be juror misconduct that Emperor Zarlak from the Planet Fremulon would deal with quite harshly. Also, the marshmallow people would likely squelch any attempt at an investigation.
