You are correct - to be convicted of a criminal offense (something for which you could go to jail), you would have to be present to waive your right to trial, your right to be represented by counsel and then to affirmatively plead guilty. It's different if it's a ticket for an ordinance violation. You should consult an attorney to help you void whatever conviction was entered.
The answer is - it depends. These are very fact-specific situations, and also depend on what "facts" are presented by the complaining witness to the police and/or DA, if they are contacted. The most important thing for your friend is to make sure he has a lawyer BEFORE the police try to speak to him. He SHOULD NOT speak to anyone about this without consulting a lawyer.
Yes, the Judge can lower (or raise) the bail. His lawyer will file a motion for bail modification. Bail is set based on a number of factors, most importantly any information that will assure a Judge that he is a good bet to show up for future court dates. Although bail is supposed to be set at the least amount that is necessary to assure the defendant's appearance in court, the seriousness of the charge also plays a big role. He should consult his lawyer to discuss these things, as they are...
If a necessary witness doesn't show for a trial in Milwaukee Municipal Court, the Judge will likely dismiss the case. This happens with some frequency there. However, if the bartender/off-duty copy wanted a citation written, i don't know that it's correct to assume he or she then wouldn't show up in court for the trial. Police officers (including one who witnessed something while off duty) would be more likely to show up than a citizen who may not want to be bothered. You may want to consult an...
The Supreme Court requires a probable cause finding within 48 hours; in Wisconsin, some jurisdictions, including Milwaukee, fulfill this requirement with a "paper" review, meaning that a court commissioner reviews an affidavit filled out by police and makes a finding as to probable cause and then sets bail. If they continue to hold a person pre-charging after the PC finding, the person is at least able to bail out (if they can afford the bail). It's important to consult an attorney to see what'...
If you get a citation, you should at least consult with someone experienced in the municipal court in your jurisdiction. Often such an attorney will be aware of the possible avenues for avoiding a conviction on the citation, such as a "hold open" or deferred judgment agreement.
Custody credit can be complicated, but the general rule is that a person only gets credit for time spent in connection with a case if that time has not already been credited to another, non-concurrent case. If he had cases in two different counties, that may be the reason the credit didn't go to the Milwaukee County case. Your son should consult with the attorney who represented him to make sure he's getting all the credit he deserves on each case.
Technically, you agent could revoke you for violating your rules (i.e., missing an appointment), but in my experience it's unlikely. The important thing is to contact him/her asap - if you can't reach him/her keep trying. If you've otherwise been compliant, you are probably looking at a lecture/admonishment but not revocation. Of course, every situation like this is dependent on the specific facts of your supervision, your relationship with your PO, the original offense and other factors.
The answer depends on the specific facts of the case. In some circumstances, police can enter without a warrant under something called the "community caretaker" doctrine. There are other possibilities as well, but they are limited exceptions to the general requirement that a warrant is needed to go into someone's home. You should consult an attorney to talk more specifically about your situation.
If you are represented by counsel, the prosecutor (DA) cannot speak to you without your lawyer being there. Generally it's better for you to let your lawyer speak for you - after all, that's hopefully why you hired him or her. They likely have experience communicating mitigating aspects of your situation in the way most likely to get the results you want.
