This is the answer.  Even if those packages don't run bad scripts, they install potentially arbitrary files, as root.  Installing a package you don't know the provenance of is essentially saying you don't care that much about security (which is a fine choice to make, but it is a choice).

The only even slightly safe solution to this is signed packages and a hairy trust system. I get the impression that a lot of platforms either do this or nearly do it now (although in at least some cases (Apple, I'm looking at you) some of this security is pretty theatrical).
