I have a very different view now. I learned during the period of the 2011 attacks (very close by), and the anthrax and then "Washington Sniper" period that I was really making myself sick with worry and unhelpful anxiety by winding along with every twist and mistaken lead and endlessly repeated film clip of horrible things being shown not because they were relevant or useful but because they existed.
This past week has been, for the US, filled with urgent news: bombing, explosion, ricin, police hunts. Very little of it needed ME to know about it in real time - although I did want reassurance that my own family and friends in Boston were unaffected, that was not done by watching the news.
In 2013, it isn't just the TV newsfeed but also Facebook and email alerts and Twitter and many of the other ways we are "updated" in real time if we choose.
This has been an anxious week. I didn't change the events by turning off the TV, but I did change my own reaction and my anxiety level. These days I think this was the most informed and mature way to approach it. It doesn't mean I "care" less. It also doesn't mean I know less: waiting until the end of an event makes me more likely to actually hear the "news."
