Citation: Citing out is a type of release from custody in which you sign a citation, a promise to appear in court. It's usually a form that looks like a traffic ticket. If everyone has decided to cite out, it is important to make sure that the people who are at risk (non-U.S. citizens, those with warrants or prior convictions, and those on probation) get cited out first.
<B><FONT size=2>Bail:</FONT></B> Bail is money you pay to the court, to be forfeit if you don't appear at scheduled hearings. A bail bondsman can put up the money for you, but you have to give the bondsman a percentage of the total bail (usually 10 percent), which s/he keeps as payment. Often, there is a pre-set bail for misdemeanors and lesser felonies which you can pay at the jail without waiting to go before a judge.
<B><FONT size=2>Bond:</FONT></B> A bond is like bail except that you put up collateral instead of paying money. Collateral is something of value, like a car or house or land.
<B><FONT size=2>OR:</FONT></B> Release on your own recognizance (OR, ROR or PR) is simply your promise to come to court for scheduled hearings without having to put up bond or pay bail. Usually you will only be released on your own recognizance if you can prove that: (1) you are not a danger to the community; and (2) you are not a flight risk-unlikely to return for court appearances. You are likely to be kept in jail if you:
