FIRST POLICE CONTACT
Lawful arrests cannot begin with police officers simply choosing to hassle an innocent victim for no reason. Even an officer's suspicion of wrongdoing isn't enough for the police to stop a suspect, not even an articulatable suspicion (one based on more than a simple intuitive hunch, that can be explained in words) is enough. But combine an articulatable suspicion with reason, and you have all that is necessary to begin the arrest process. To stop or detain a suspect, the police must possess a reasonable articulatable suspicion that the arrestee has committed or is about to commit an unlawful act. If such a suspicion exists, next follows probable cause -- the confirmation of the suspicion, or the discovery of a criminal offense -- after the initial police contact.
If time permits, the wise officer will appear before a judge to explain his opinions regarding reasonable suspicion and probable cause to obtain an arrest or search warrant. But such warrants are not necessary in all circumstances and are not sought when the police fear that evidence, or a criminal, might vanish if time is taken to obtain a warrant.
Whether arrested by probable cause or by warrant, the next step is the beginning of police custody -- the point at which the arrestee's freedom is taken into the hands of the arresting officer and law enforcement agency. He will be handcuffed, placed alone in the back seat of a squad car, and transported to jail. It is important to understand that even during an illegal arrest, it is unlawful to disobey the arresting officer. Immediately upon his arrest, Miranda warnings are usually given.

FELONY BAIL
If the arrest was charged as a felony, bond will not be set at the police station on the night of the arrest. The arrestee will be required to spend the night in jail until sometime, usually the next day, when he will appear before a judge who will hear the facts and set bond.
At this appearance before the judge the defendant will not be given the right to court appointed counsel. He will be given the right to future court representation, but is seldom appointed a Public Defender for the first appearance process. The State's Attorney will tell the judge what crime is alleged, tell him about the defendant's record, and the judge will choose the appropriate bond amount. If the defendant speaks up and gives the judge a reason, he might set bond lower than the amount requested by the State's Attorney. If the defendant speaks up and says the wrong thing, the State requested amount can be increased, or the defendant can be charged with contempt, or maybe further charges arising from the original incident. Anything said in court is fair game for the prosecutor to use to amend present charges or file further charges against the defendant or those who speak up in his behalf.
At the bond reduction hearing, private counsel can participate, but because no Public Defender is available, defendants usually appear without counsel. The States Attorney explains to the judge why this particular offense warrants a particular bail, and recites the defendant's criminal and arrest record to the judge. The defendant will be given a chance to respond to the recommendation, but usually the State's Attorney gets the bail he suggests.

BAIL DETERMINATION FACTORS
The judge considers the severity of the offense and the defendant's criminal record when deciding how high to set bail, but certain other factors are available to suggest lower bails. Among these are:
1.) Defendant's period of residence in the area. If he has been a lifelong resident of the County, his bond may be reduced based upon the expectation that the defendant is unlikely to move away during the criminal case.
2.) Defendant's ties to the area. If he has many family members in the area, he may be considering the effect on his family should he flee the jurisdiction, and if he does, he'll probably return sometime, and be rearrested.
3.) Employment history. The guy with the same job all his life is unlikely to voluntarily leave that job because of the criminal charges.
4.) Property in the area. Defendants with financial ties to the area can usually be depended upon to remain here to care for their property.
5.) Financial obligations. Defendants whose flight from the jurisdiction would result in foreclosure of a mortgage, or default on a loan, have great incentive to comply with the terms of bail.
6.) Family dependants. Likewise, if others depend upon the defendant for their support, flight is unlikely.
7.) Special circumstances. Such as family members with extraordinary medical needs or hospitalized immediate family members.
If you get the opportunity to visit with a jailed loved one before the bail hearing, go over this list with him. Remember that there will be no attorney to speak for the defendant unless private counsel has been retained and can get to court before the first appearance. If the bond amount requested by the State's Attorney is excessive, the defendant may be given the right to respond to the State's request for bond.
Oftentimes, a concerned family member in the audience who respectfully asks the judge for the opportunity to address the court, might be permitted to help the defendant explain his financial predicament to the court. The judge needs information to believe that the defendant is solidly committed to the community and will not flee the jurisdiction if released on bail. Tell the judge every reason you can for him to release the defendant if you are given the opportunity to speak in the defendant's behalf -- but say nothing to incriminate him about this arrest or any other, and be respectful!

BOND REDUCTIONS
When the court sets bond (and bail), the amount can be reduced later. If an attorney files the appropriate motion, and can convince the court usually of information not presented when bail was originally set, the court can reduce bail. If a request for bond reduction is denied by the judge, don't expect him to change his mind later unless the defendant presents important new reasons to be released.
