1. Just because you can do something doesn't mean you should #2
In which Twitter disables the account of freelance journalist Guy Adams (who writes for, among other publications, The Independent) after he savagely criticized NBC's tape delayed coverage of the Olympic Games, and in the process of doing so, published the email address of an NBC executive that people should complain to.
It appears that Adams violated a Twitter rule that forbids the publication of private email addresses. However, as Adams has pointed out, this was an NBC employee email address, not a private one, and email addresses within NBS are deeply stereotypical to the point of being totally predictable in most cases. Anybody with a functioning brain could have guessed the person's NBC email address in thirty seconds or less given their first and last names.
There was no upside to banning Adams from Twitter. All it did was make Twitter look like a bunch of over-zealous censorious nitwits in the thrall of NBC. That reduces their internet credibility. If they have any sense they will reinstate Adams and find some way of admitting to error. I doubt that this will happen, since large providers of any service generally do not have a well-developed ability to say "we are sorry".
2. Note to the Macho Men who think they could have stopped the Aurora CO shooter
Jim Wright over at Stonekettle Station already eviscerated (in passing) the people laboring under the delusion that one or more heroes armed with concealed handguns could have stopped the Aurora CO shooter. Here is another short sharp put-down of the closet Rambos and Chuck Norris wannabes.
