Humor can actually be better than medicine sometimes or in this case candle vigils. Ziggy post that rampage 9/11 picture so he doesn't feel like you're just a British hater.
And the other guy said he heard it might of been a diversionary tactic for a much bigger attack. 9/11 was much more devasting then today's London explosions. So 40 + people getting killed could be a diversion for a much more deadly attack in the near future. This isn't London's 9/11. I fear that is still to come. Madrid bombings took out how many people? Over 200?
