In the end of this video, Dr. Park Dietz says:

Because every time we have intense saturation coverage of a mass murder, we expect to see one or two more within a week.

Is this true?

    Interesting. If I'd had to guess, I'd say it's so called "Baader-Meinhof Effect". After significant shooting media focuses more attention on anything shooting related. Thus reporting even less significant ones, which wouldn't make news otherwise. – vartec Jun 23 '15 at 8:44
  • The formulation we expect more is ambiguous. – gerrit Jun 23 '15 at 9:54
  • @nomenagentis It sounded like he meant "we" as in "the people who study these things", based on context. There's a transcript here – ike Jun 23 '15 at 12:30

    Unless he's got a very different definition of "mass murder" I'm afraid he is talking garbage. Even in the US there are only about 3 mass killings a year, and they certainly all don't happen in the same week. If nothing else we'll know in about a day if there was another killing a week the Charleston shooting. – DJClayworth Jun 23 '15 at 13:27
