People, people. You need to read the STATE the poster is in. Georgia is one of the the places where a citizen can get a warrant. I suspect he means he's applied for a citizen's warrant. The next thing that happens is a warrant application hearing. This is more informal than a trial. The judge himself may ask questions to get to the bottom of the situation, still there must be probable cause and the accused can refute that cause. You're allowed an attorney but one is not required.
Note that the accused, if indigent, can get appointed counsel for this. You as the accuser can not.
Once the warrant is issued by the judge, then it's now out of your hands. As stated by the previous poster, once charges are filed, it is the STATE (in the form of the district attorney) that prosecutes from there.
