As a general thread FYI, the purpose of a misdemeanor arraignment (in FL) is to inform the defendant of the charges against them and to enter the defendant's plea into the record. An attorney can stand in.What? That makes no sense.
As for what it looks like in real life, usually, the court will just call one case after another off the list of cases that are going to be heard that day. That list is informally called a "calendar" of cases, although some places might call it a daily docket of cases. When called, the parties, or their attorneys go to the podiums. The state announces on the record what charges they are filing, or if they have decided to decline prosecution, or if they're binding up the charges to a felony, or any other procedural resolution (transfer to Juvie, transfer to special prosecutor.) The defense will often waive the formal reading of the charges. (In fact, I can only recall twice that I insisted the charges be read into the record.)
If the defendant is unrepresented when called, the court inquires as to whether counsel should be appointed (and counsel will be if the defendant is indigent and the state is seeking jail time in the case). The case is passed to later on the calendar. After the appointment an attorney, the case is passed to later on the calendar. When called again (hopefully after enough time for a quick consultation) the defendant is asked to enter a plea, which is traditionally Not Guilty. If a defendant is pro se, or does not qualify for the public defender, the court routinely just enters a NG plea on their behalf. Often the just-appointed attorney will have to enter a NG plea as their client is whisper-demanding, Wait, what are you doing? What's going on? at their elbow. You also demand discovery (the state usually has something in the file to give you), and demand a trial by jury.
The state will often have a plea offer that they will convey to the defense for the first time. If there's a chance the defendant will take the offer, the court is told that an offer needs to be conveyed and the case is (again) passed to be recalled later on the calendar. But, obviously it's best practice to simply do due diligence and review the case before your client takes any deal. So some judges will just set a trial date regardless.
The setting of a future trial date usually ends the arraignment. The trial date is more of a placeholder than anything - many FL county courts will set 30 cases for trial on the same day, knowing they can try one, maybe two cases across the whole week. In the meantime, some of those cases will plea out (the attorneys just calendar them to take the plea after the arrangement calendar.) Other cases will need continuances beyond the trial date. Some cases will be subject to speedy trial demands, and some won't. Usually a courtroom will end up with 0-7 cases that could be tried on any given trial day. Some of those resolve, some get continued for different reasons, and some actually get tried. Usually, it's the older cases, cases with speedy trial issues, or cases with limited witness availability that get tried first.
So, no. Kraft does not have to show.
And no, whatever his trial date is set for very likely won't be the actual trial date, whether he wants to plea or try it.
