For whatever reason, the site makes you click the direct link to the particular comment you want to flag. I.e. the timestamp link. For posts you generally always click a direct link (via the comments link) so that's why it's obvious for posts.
If you opt to have "showdead" enabled in your profile you'll still see flagged comments but marked as [dead]. In this case you can also vouch for comments in the same fashion (or add another flag to make it harder to be vouched for).
I think it's something like >30 karma to flag/vouch posts (so you should well qualify). This means users actually gain that well before the ability to downvote... but the site sure does a good job of hiding that from them lol.
