The Aurors under Granger, as a matter of policy and habit, don't say any word that contains the syllable “cru-”. “crew” becomes “team”, “crucial” becomes “essential”, and so on. “Cruciatus Curse”, of course, becomes “Torture Curse”. They also refer to the Imperius Curse, which takes control of a person's actions, as the “Control Curse”. The PTSD issue is much less for that one, but the “false alarm” issue is especially relevant. A casual, indoor conversation is exactly the situation where you need to be the most vigilant against people actually casting the Imperius Curse.
From left to right: Arthur Weasley (Head of Misuse of Muggle Artefacts Office), Pius Thicknesse, Bartemius Crouch, Amelia Bones (Head of DMLE as a whole), Hermione Granger (Head of Auror Office), Kingsley Shacklebolt. The books don't specify exactly what career path Crouch took before ze became the head of DMLE, but I decided it was natural that ze had been an Auror at some point along the way.
Arthur Weasley will wake up when they start talking about misuse of Muggle artefacts, which will probably be never.
Tonks is one of the trackers Granger refers to. Ze's very good, but people who haven't worked with zem sometimes have trouble believing in zir skills because of the informal, casual way ze approaches everything.
In the books, Tonks says ze almost failed the “Stealth and Tracking” portion of the Auror examinations, because of zir clumsiness. Because of this, some people might assume that ze wouldn't be a tracker. I chose to assume that ze got a bad score in Stealth, but made up for it by being very good at Tracking.
