In this case it seems entirely reasonable as you say.

However. Let me straw man a bit here.

In the case of, say, someone being murdered with "a 16 inch double ender" at a themed orgy... Well, let's just ask google for anyone who has searched for an appropriately inclusive set of terms in the past 3 months. It's logical that someone who gets flagged in this data set could be the culprit right?

Gosh I sure hope none of the data gets leaked or misused in any way by the fine upstanding people who get access to it.
