What happens if you are arrested on a misdemeanor warrant after the statute of limitations has expired?
There is no statue of limitations for a crime. It is not the same as an old debt
You get handcuffed, read your Miranda Rights, Took to the nearest station, Finger printed, Mug Shots, Strip Search, Now if its a misdemeanor you usually get released If your staying for awhile you will change into your colors & get shown your bunk. There are many procedures, depending on when, where and for what you were arrested.
If the warrant is for a misdemeanor offense, you will not normally be arrested unless you are stopped for a traffic violation or if the police are called to a scene, where you may be. If it's a felony warrant, for a serious violation, such as murder, you will be tracked down, even in another state, and be arrested and extradited.
