It started in China, they didn't respond as they should have in terms of reporting it, and we've exacerbated it by making a complete horlicks of our response and continue to do so.

If you think that exculpates our Government for what happens here, then there's no hope of a reasonable discussion. In so many ways, we have failed to act to protect our citizens at the right time. That's unacceptable when a Government's first priority should be the safety of it's people.
