Your claim of violating copyright laws holds no water.  
HTTrack only saves freely available material that any 
person's browser can access.  Someone could do it by hand 
with "Save As...".  Even IE has offline browsing, I believe. 
 What happens to that material afterward is up to each 
person, and this is not the software's fault.

Our library uses the software to capture our state's 
websites for preservation purposes, many of which are now 
offline while we still hold an in-tact copy.

The legitimate uses far exceed the abusive use.
