IMO i'd say you are both correct, you would need to shoot at the harlies (if you can) that is just the way that i see it.

Also this fits fluff wise as the would still block line of sight.

Veil of tears DOES NOT make them invisible. it just makes the people trying to target them ignore them. they are still there and can be seen, just cant be shot at and as such block line of sight.
