Would you care to substantiate this idea that the district court which rejected the US extradition request simply "didn't take the request seriously"? Being that this is an incredibly insulting accusation to make about the Polish legal system?
Had you bothered researched the matter a second or two (before making up a condescending opinion about it) you would have readily found the basis on which that court made the decision that it did. A very specific, and universally understood (and generally accepted) basis, in fact.
