Poor taste, and questionable financial backing. I haven't read much on it, just about the bickering from both sides. I don't think they are putting a minaret on it (yet), but I suppose they will do what they want. I also hope the feds to dig through the finances and bug the place. If the imams start preaching DTA and celebrating the 9/11 "martyrs", I don't imagine the NYFD will respond quickly when the place catches fire.

Can they? Yes. Should they? Probably not.
