Valid point D9, but to be fair toward Heimdall, The Dark Elves utilized very ancient Dark Magic against him. With Loki as Odin, I think Heimdall is sort of aware but feels it is not his place to tell anybody including Thor or the Warriors Three. I base this off of when he got suspicious of Loki during the first movie after the appearance of the Frost Giants.
