Discuss it with the attorney you retained. Your attorney will not care about OUR opinions. Incidentally, cops, lawyers, and even judges use the same documents time and again but modify them for different cases. What matters is if the factual allegations are true. If you think typographical errors win the game, then you plotting a course that will end in disaster.
Can an attorney make an officer look foolish on a stand by comparing arrest reports a nd pointing out similarities? Of course. It can also backfire, since most people make errors, and if you want to see evidence of how people react to such tactics, then go onto Facebook and criticize someone's spelling/grammar.

I agree with attorney Dillingham. Review his answer. It addresses your concerns and explains how the facts you relate will be interpreted.
