Tweets are the most effective and instantaneous way of getting a message out.
although the media probably found out about the shooting not through twitter but by listening to police radio chatter, the next step for them to find first-hand accounts is not facebook, but twitter, which is open for everyone to see.
Exactly. The media are not “vultures” for seeking out someone who has already been voluntarily sending out information to large numbers of people.
There are many reasons they are vultures, but that is not one of them.
