The majority of arrests are made by the state government. However, the federal government also has a prosecutorial arm and the jurisdiction where they could charge you with crimes. Similar procedures are afforded on both the state level and the federal level, so if you are arrested in a federal case, you’ll pretty much go through the same procedural steps as you do at a state-level case. They’ll go into custody, a possible bail or bond will be put over your head and then you will fight your criminal case and you’ll also be afforded with the right to have a lawyer at all the stages and proceedings of your federal case.
