Why would bomb-sniffing dogs be sniffing for something that did not exist at ground zero?
1. Zero audio evidence for demolition explosions
2. Zero video evidence for demolition explosions
3. Zero seismic data evidence for demolition explosions
4. Zero demolition hardware evidence within the rubble of the WTC buildings
5. Zero evidence the WTC buildings were structurally pre-weakened.
This is what happens when a building is not properly pre-weakened.

Zero evidence for WTC demolition explosions, but overwhelming evidence that debunks the claim that demolition explosives were used.
