Police in Georgia can arrest someone for family violence without a warrant, and they can do so even if the alleged violence did not happen in front of them. State law authorizes a warrantless arrest when an officer has probable cause to believe an act of family violence has occurred, an exception to the usual rule that a misdemeanor must happen in the officer’s presence. The probable cause standard, not direct observation, controls.
Officers responding to a family violence call assess what happened and who was responsible. When the evidence points both ways, the law directs officers to identify the predominant aggressor rather than arrest everyone involved, weighing factors such as offensive versus defensive injuries, any threats, and the history between the parties. This focus is meant to avoid arresting a victim who used force defensively. The same probable cause exception lets officers act on physical signs, a frightened account, or injuries documented after the fact, so an arrest can follow an incident reported only once the immediate danger had passed.
Older practices have given way to this approach. Cooling-off periods that once delayed action no longer stand in the way of an arrest supported by probable cause, and officers document the relationship between the parties to establish that the family violence provisions apply.
Once an arrest is made, the case takes on a life of its own. The alleged victim cannot drop the charges, because the state decides whether to proceed. The arrest itself sets the prosecution in motion, and the choice whether to continue shifts to the prosecutor the moment it is made, regardless of what the parties later want.
