Whoever is near the microphone becomes the account. The people at the front of the room, the ones who arrived early, the ones comfortable speaking, get recorded, and everything said in the corners disappears. The record is shaped by placement long before anyone decides what it means.

In any situation where a version of events is being captured, ask who is positioned to be heard. If you have influence over the arrangement, move the microphone, literally or otherwise. Going to the quiet part of the room changes what the record contains.
