1,500 chicken culled in an exercise

This is the most realistic exercise we ever had to protect ourselves from bird flu. 1,500 chicken coming across the causeway were culled as part of a major exercise. As exercises become more serious, the more realistic the better will the participants learn and be prepared for the real thing. The next exercise on a building collapse will probably see the falling of a building with living people inside. The casualties will be collateral damage and necessary to make the exercise real. And the simulation of a terrorist attack, I can't imagine how real it can be. Wonder if any country will conduct military exercise involving live ammunitions and life being sacrificed? Iraq is a kind of life military exercise to test weapons and systems I supposed. Animals or lives are dispensable to achieve our aims of protecting more lives. All those who are protesting against cruelties to animals involved in lab test please buck off. If we can just culled 1,500 chicken for an exercise, what is a little pain and suffering. We are progressing very rapidly.
