All jails look about the same, lots of concrete and metal.
They are designed to hold people that have been convicted of committing a crime and have received less than one-year as a sentence by the judge. If they receive more than one-year, they are sent to a correctional facility operated by either the state or federal government. Jails are also where people stay until they appear in court or have a bond hearing. A bond is a promise to appear in court when ordered by the judge. The bond can be as little as giving their word or as much as several thousand dollars.
