Do they have a guideline for WHEN subtitles are used? I remember sitting in a hostel common room the day after Mark Duggan was murdered[1] and half joking "Are they giving that Scottish guy subtitles as a joke?" and being told "This is a very serious situation". The previous night, the "mates" had been "joshing" me about how much more violent America is... then their eyes went wide when I was like "Well, that's a BRITISH cop car on fire, I'm switching to water... it's gonna be fun finding our way home... doesn't the queen live near here?" (To be fair, the "chavs" were very respectful once they heard an American accent and let us walk home, but part of that may have been because they didn't grok that they check us for guns at the airport and that rumors every bald black clad hacker is in the CIA are greatly exaggerated so they totally could have knifed us all and taken our iPods, lolllll.)
