NO.
Boston has Muslims, I was driven around the city by a Muslim cab driver--a very nice fellow, to be honest. But there's a "colony" there, apparently.
Now, to the point: There's NO REASON why the Irish would ever want to bomb American cities. For Heaven's sake...they've even stopped the bombings in Ireland/UK.
Don't forget: this has all the hallmarks of a PALESTINIAN-type bomb. They do this--ball bearings, nails, even coating the shrapnel with AIDS, Hepatitis, and other diseases, so that even if you're scratched lightly, you might contract something to become another victim for their Moon God.
Remember that spate of Pizzeria bombings in Israel? Went on for several years while they talked "peace, peace" but there was no peace.
That terror against Israel only ended when they built that large wall.
This has all the hallmarks of a more Palestinian-flavor terror campaign. It fits their modus operandi.
Did you read the last line of my post. i was commenting on the style, but said if it were 30 years ago I’d look at the IRA. As for the muzzies, every big city in America has some collection of Muslims. This was hardly the work of a bunch of local muzzies getting together after Friday prayers. This was planned and carried out with professional panache. Now if I was looking in Boston, I might look for a local muzzie, or i might look for some balding red haired boyo living in Southie who can pass easily for a local wearing his Bosox cap and who just might have some experience with this sort of stuff when he was learning the trade back in Derry and is hiring out to the highest bidders.
