“the thing looked like a bomb!”
Given the fact that bombs use clocks as the timing mechanisms, the component missing from the device was the explosives necessary to convert it into a functioning IED (Improvised Explosive Device) made from a disassembled commercial clock radio. In other words, Obama and the White House are inviting and celebrating a Muslim child because he took to school a commercial clock radio that had been disassembled and mounted into a portable case capable of housing the addition of explosives needed to complete an IED. How is that any different than a child, Muslim or non-Muslim, taking an unloaded firearm to school?
