Keeping Your Story Straight
Furthermore, when I have brought up the issue that the large contribution (although not a majority) of comets to the impact flux means we can not come close to 100% protection of Earth from Impacts regardless of how many orders of magnitude you overpay for a detection system, you have previously denied both the significance of their contribution and that the warning time for them will be too short to deal with.
