Good catch.
It is a possibility...The consumers of halal meat are by definition “permanently aggrieved”, with a loooong history of resorting to violence whenever they feel their “religion” has been disrespected. However, a possibility is all that it will ever be, because any data that might settle the matter will be quietly kept from the media. Look at the mohammedan murderer down in Rio : The media didn’t even mention his religion in quite a few accounts. BTW, that killer’s instructions on what to do with his carcass are virtually identical with those left by a few of the 9/11 terrorists, which strongly suggests that the Rio monster did indeed regard his murder of little school children as an act of jihad.
