I read the BBC story on this numerous times and the day after it happens the attacker was described as a white man. As the attack occurred in a non plaid and maple syrup part of town I considered it might be an antibiotic immigrant backlash attack, which as things get worse will happen. Now, crickets...
German bus stabber described as a " German citizen." See, you forgot about the bus stabber already! Early reports said Iranian extraction and the all knowing " no indication of radicalization." None it wasn't either, nothing to see here, move along and we don't release the suspect's name due to privacy laws.
