This is because if you download anything from the net, it would be 
trivial for somebody to add a scripted called "ls" or "cd" into that 
archive, then you'd do something simple like:

	tar -xvf evilfile.tar
	cd evildir
	ls

and suddenly be executing the "ls" script that came from the evil 
archive which, besides performing a "real" ls to show you what files 
(minus their own scripts) it could then modify all of your files, 
take over your computer, send your credit card information to 
Elbonia, cause flooding in your basement, and make your cat/dog's 
hair fall out.
