Display of Police guns found with melted concrete in the ruins of the WTC

The following web site contains photographs allegedly taken at the NY Police Museum,
showing police guns melted in with concrete found in the rubble of the WTC.


Has anyone seen this display in reality?
This seems to indicate very high temperatures.
Just curious.

Very interesting find ..

One of the signs says :
"Fire-temperatures where so high that concrete melted like lava"
Yeah right and the Earth is flat and gravity is only a "theory" .
