Sick. Prayers are with all of England, obviously.
Though, the one thing I'm going to hate is that the cable news media is going nuts over this. Anytime something big happens they just go nuts, Reagan's Death, Tsunami, Shiavo, etc.
Not to say this isn't newsworthy, of course it is. It's a tragedy. However, with every news station looking for their own angle and exclusive, sometime real news gets ignored. But right now the news will be bordering on exploitation of the bombing.
