apt-get can be configured to only download the files and not installed them.

This it does as root however. However apt-get can also print the URIs (see
the man page for specifics) so that you can download things via whatever

I don't perceive a security risk in downloading as it is basically slapping
bits you got from a socket onto a file.

As I've stated previous, currently Debian doesn't validate signatures it
only does an md5 checksum on files. Should an attacker modify the original
archive then they can easily send bogus packages to you (by modifying the
packages file).
