Thanks for that information.
So when there is a outstanding warrant, the underlying facts of the allegations or the charges against the person are not relevant. The warrant only deals with the person being extradited back to the jurisdiction hearing the underlying criminal charge.
When a police officer is executing a warrant, they do not have any knowledge of the facts of the case. They are bound, by law, to arrest the warrant and hold that person until the jurisdiction that issued the warrant comes picks them up. So, essentially, a warrant only deals with bringing the person back into court and nothing else (they do not deal with what the actual case is about).
The hard part is determining when, if at all, the jurisdiction that issued the warrant will pick the person up. That is because it all depends on the jurisdiction that issued the warrant. However, with felony cases, the likelihood that the person will be picked up is very high as warrants for failing to appear for a felony is much more serious than misdemeanor failure to appear warrants. On top of that, because IL and WI are neighbors, the chances that they are picked up is even higher because there is less travel and less expenses involved.
