H,
Never happen. Manhattan is as liberal as they come, and it got the worst of it.
The timeline for a Sep 11th-scale attack on Boston would go like this:
H-hour: catastrophic terrorist event. Fire, water, rubble.
H+10 minutes: Blame Bush.
H+12 minutes: Rush out and burn an American flag.
H+1 day: Spit on Bu$hHitler's jackbooted $oldier$ as they restore order, assess damage, and provide help.
H+3: Riot for lack of lattes and chardonnay in relief supplies. Cambridge turns back refugees on bridge. Entire Harvard faculty takes sudden sabbatical. Blame Bush.
H+1 month: Boston refugees re-located to Worcester and Springfield; had no idea there were even people between Rt 128 and California. Blame Bush for not relocating them to Nantucket.
H+6 months: Newcomers continual victims of local criminals and gangs in central and western MA; rainbow flags ineffective against Glocks. Blame Bush for rampant crime that's existed there for 30+ years.
H+1 year: Encounter session and healing drum circle on charrred remains of Boston Common. Beg forgiveness from every non-white, non-Christian foreign person available. Blame Bush.
LOL!
As a Massachusetts resident, nothing could be closer to the truth!
