In the days when all Christians lived under Christianized Roman Law, it would have been perfectly reasonable to speak of a "Christian legal system". In Islam, there is a strong and in many places effective, movement to apply the Sharia as the only law, not only in terms of content, but in terms of procedures. In these places, it is reasonable to speak of a "Muslim legal system" without absurd generalization.

In Pakistan, the movement has not completely succeeded. Its influence (as well as the influence of U.S. military aid) must be considered in analysing the likelihood that extradition requests to Pakistan will succeed.

Also, don't forget that demanding a right to try a foreign national for a crime committed in another country just because the victim is a U.S. citizen is a very strange precedent. If an American (or Canadian) murdered a Pakistani national in America, he would be tried in America, not extradited to Pakistan. The combination of a demand for extraterritorial application of American law which would provide for capital punishment when local law (in this case Sharia) would not is very iffy.

I believe congress did pass a law making it a Federal crime to commit acts of terror against US citizens on foreign soil. Whether or not the country in question would consider extradition under any type of treaty we may have with them...I don't know.

I know the circumstances are a little different, but we did sort of demand the extradition of UBL from Afghanistan, and you see the results of their failure to comply.
