Prosecutors are to be forbidden from misstating the law or advancing positions adverse to authority, and certainly not without disclosing as much and providing case law for such a reckless path.
Further, prosecutors opinions have ZERO place in the courts and this has been clearly established many many years ago.
However, most wish to win at any cost and their rebuttals of the defenses closing argument generally always crosses over all reasonable lines.
"[Prosecuting] attorneys are government officials and clothed with the dignity and prestige of their office. What they say to the jury is necessarily weighted with that prestige. It is their duty to see to it that those accused of crime are afforded a fair trial . . . . [para. ] It would be a sad day for the administration of justice if this court were to condone the substitution of the personal belief of the district attorney . . .that the accused should be convicted because the district attorney thinks he should, for what the law guarantees -- a fair jury trial."
“The statement `we try to prosecute only the guilty is not defensible. Expressions of individual opinion of guilt are dubious at best...This statement takes guilt as a pre-determined fact. The remark is, at the least, an effort to lead the jury to believe that the whole governmental establishment had already determined appellant to be guilty on evidence not before them.” <good luck finding a panel of jurorists that don't really have that mindset anyhow> (Hall v. U.S. (5th Cir. 1969) 419 F.2d 582, 587; see also Cargle v. Mullin (10th Cir. 2003) 317 F.3d 1196, 1218 ["'It is always improper for a prosecutor to suggest that a defendant is guilty merely because he is being prosecuted.' [Citations].]")
Improper arguments in rebuttal are deemed more likely prejudicial. See United States v. Carter, 236 F.3d 777, 788 (6th Cir. 2001) (finding significant "[t]he prosecutor's improper comments occurred during his rebuttal argument and therefore were the last words from an attorney that were heard by the jury before deliberations"), cited by U.S. v. Sanchez, 659 F.3d 1252, 1259 (9th Cir. 2011).
Your attorney, as part of the local frat club of cronies, are in it to uphold the system and make money. This is why prosecutor abuse and misconduct is seldom challenged in America and allowed to be the rule, instead of the exception.
