Probably for the same reason your state's officials allow them in New York. A quick check on Google Maps finds your state has no less than 10.
LOL,I don't know about the number of cemeteries in my State but am fully aware of Islamburg in Hancock. NY should be so proud - not.
My original point was, if a State allows muslim cemeteries then they shouldn't be "flabbergasted" that a terrorist was buried in their State. They are the ones who opened that door, so they should just grin and bear it.
Maybe they can apply the wood transport law to dead terrorists. It cannot be transported more than 50 miles from place of origin.
I wonder if IRS is going to investigate the person who donated the plot.
