Isn't Boston the home of NORAID? I wonder how many of the people unwittingly mixed up in this (apparent) act of terrorism were quite happy to pump money into the IRA for years? Sorry, don't want to put a dampener on things. That little point doesn't change the pointless suffering of the victims or the amazing work the emergency services are certainly doing. Just think it will be interesting to see Irish American politicians denouncing terrorism (if that is what it is).
Like I said, I'm not wishing to disrespect the victims of this disgusting act in any way. The victims of terrorism are always the most innocent.
