It is against the law in most places in the US to start ANY open fire without a permit from the local authorities, who are under no obligation to issue one. This has been an issue with chametz burning erev Pesach and baruch HaShem our leaders have in many areas worked with the local fire departments to have safe local burnings. Do not expect such cooperation if you want to burn somebody’s religious items as a protest.
Furthermore, Gen. Petreaus complained that even the rumors of Koran burning are endangering the lives of American soldiers in Afghanistan who are trying to fight the Muslim fanatics there. And of course, if Korans get burned, sifrei Torah are next; this so-called Pastor Jones is also an anti-Semite who has endorsed the hateful actions of the Westboro Baptist so-called church whose members carry protest signs saying “God Hates Israel” in front of Orthodox synagogues.
