Four years later, nothing changed
I guess it remains to be (hopefully never) seen how we cope and where the best source for information is, but in terms of when the July 7th bombings happened in 2005, the Internet remained a poor source of information. I recall getting very frustrated with news sites and just finding a TV when in the London office.
What has changed for the worse today now however, is TV's incessant guesswork and subsequent hauling in of "experts" and little done to retract them. If you recall, when the Norwegian mass murder happened back in July this year, the immediate suspicion was of an Al-Qaida attack, which quickly became fact, and quickly resulted in pundits (or experts as they were called) being dragged in to explain why Norway was a target. Within 24 hours it was clear it was actually the opposite, yet the same pundits were in with a brand new tact with no mention of their previous expertise.
It seems we've now moved to a full 24-hour rolling news where in absence of facts, we've accepted poetic licence to elaborate on theories as fact until we're told differently.
