I was a cop for lots of years and I agree. However, just the fact that Islam is at the top of the motive list is rather telling. If the victim had been arguing theology with a Buddhist, Dominican, or Rabbi, then I doubt religion would even be considered as a motive. Either way, makes me glad to live on a very rural ranch.
Well, the Buddhist would self-immolate, the Dominican would come cast Holy Water and commence with the rite to cast out Lucifer and the Rabbi would..........what would the Rabbi do? None of the 3 have anything in print telling them it is OK to kill unbelievers, as compared to muslims.
