How can we scare you tonight?

I'm beginning to think that the purpose of the network news programs is to keep American in a state of constant fear. Right now they are busy pushing Ebola, though the chances of it becoming a national epidemic are infinitesimal. Today, they are showing signs of leaping on the, "Isis could attack here" theme. Another non-possibility. But every day brings new, and false, reasons to be wary, fretful, paranoid, or downright panicky. I guess they feel if we are in a state of anxiety, we will check in with them regularly for some comforting news, which, by the way, we're never going to get. Good news is not good for ratings.
