I hate to nitpick about grammar in the context of such a grave topic, but the passive voice is not always bad, and you could make a plausible defense of its use here. The most common reason for using the passive voice is when the subject of the sentence is more interesting than the object or had already been mentioned in prior sentences, and thus is more familiar to the reader. Using familiar names and ideas aids in the overall flow of the piece and is considered good style, even at the cost of weakening a verb.
