A warrant for unpaid court costs?!? That seems a bit severe. Here in West Virginia all they do with unpaid fines and court costs is not let you renew your drivers license until they are paid.
The first thing that came to mind was “Statute of Limitations”. But, I suppose once you flee the jurisdiction, the clock stops.
I remember that about a year before he ran for President, Barack Obama made a splash locally because he returned to the Commonwealth to pay outstanding parking tickets in Cambridge, from his Harvard days. He could have been arrested at the 2004 Democratic convention in Boston, where he first came to national attention. Sounds like a missed opportunity to me.
Here in Pennsylvania some Democrat controlled money-grubbing boro near Pittsburgh jailed a woman for 140 bucks in unpaid wage taxes.
