A possible hate crime in Orlando?

Arson a Muslim 'heartbreak'
Someone torches house on planned site of Islamic cemetery -- it may mean delays

These eight acres of oak hammocks and horse pasture in east Orange County are a landmark for area Muslims. The land is the planned site of the area's first Islamic cemetery. For the first time, Muslims will be able to bury their own.

Then early Wednesday morning, someone forced open a door of a house on the property, lit a broom in the kitchen and set the empty house aflame.

Investigators concluded the fire was arson. Now they and leaders of the Islamic Society of Central Florida wonder whether the motive is anti-Islamic hate.

Riddle me this Patman. How do you know the motive before you arrest a suspect?
