Shari'a law here in the U.S.?

LGF has posted a piece by Pittsburgh attorney David Kennedy Houck on Muslims challenging our U.S. Constitution.

First in Europe and now in the United States, Muslim groups have petitioned to establish enclaves in which they can uphold and enforce greater compliance to Islamic law. While the U.S. Constitution enshrines the right to religious freedom and the prohibition against a state religion, when it comes to the rights of religious enclaves to impose communal rules, the dividing line is more nebulous. Can U.S. enclaves, homeowner associations, and other groups enforce Islamic law?
