The article reports:
Ahmed Sheded, president of the Islamic Center of Jersey City, was among those attending. He wore a business suit instead of Muslim religious attire "because that might agitate people."
"We feel this is something that was very far away from our community," he said afterward. "A real Muslim can't do that. Any religious person who believes in God cannot do this, even to an animal."
I don't know about Mr. Sheded's acquaintance with Islamic history, but it is filled with this sort of thing from Mohammed up until today in the Battle of Iraq in the War on Terror. Put the blame where it belongs: serious Muslims.
