Without the right to a speedy trial, a person could be locked up for a very long time without ever even hearing the charges against him. Legal counsel means a lawyer. Everyone has the right to have a lawyer, even if they can't afford one. The government has to provide one to help defend poor people accused of a serious crime. Everyone has the right to know who is accusing them of a crime.
People have the right to a jury trial in most civil suits.
If a person is involved in a civil case, like an accident claim, they can choose to have a jury make the decision rather than depend on the judge's decision alone. In suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise reexamined in any Court of the United States. How much money should be set for bail depends on how serious the crime is. A judge cannot just charge a person an outrageous amount of money for bail because he doesn't like him or because he doesn't like a member of his family. Also, the punishment must fit the crime.
