My last blog post was about hiding clues in subordinate clauses, and I just talked to someone who uses grammar in a different way to hide information. (It's been a great week for grammar tidbits!)
An old friend who is a lawyer says he always uses active voice in his briefs except when he has a piece of information that looks bad for his case. Then he switches to passive voice because he thinks people gloss over passive sentences more easily than active sentences. He thinks when something is in passive voice, it doesn't draw as much attention.
Interesting approach. If you're a lawyer, do you deliberately switch between active and passive like this?
