Hi, There is probably no steady long term increase however there MAY be some short term "bumps" or "spikes" due to a vicarious reinforcement effect. This journalistic piece from On The Media stuck with me when I heard it 2.5 years ago. _http://onthemedia.org/yore/transcripts/transcripts_100606_c.html_ (http://onthemedia.org/yore/transcripts/transcripts_100606_c.html) Nancy Melucci Long Beach City College Long Beach CA

(I'm excluding war-time atrocities here). The simple asnwer to your question appears to be "No". I assume that you're referring to "mass murders" in contrast to serial murderers (i.e., the murderer kills more than 4 people in a limited period of time). There probably is good data on this but I haven't been able to find it (I haven't been looking long, though). There is an interesting passage on mass murder in Elliot Leyton's "Hunting Humans" which is available on books.google.com at: http://books.google.com/books?id=nhARuP0vLgMC&pg=PA244&lpg=PA244&dq=%22mass+mu rder%22+frequency+fbi&source=bl&ots=d21KQ6PHCI&sig=rdy9tpg1_zXji5UKhBAPll0D8XY &hl=en&ei=_5PWSeTmLoTWlQfw-5ndDA&sa=X&oi=book_result&ct=result&resnum=1 or http://tinyurl.com/c3lejc An interesting comment made by Leyton is that mass murderers have not been analyzed much by the FBI (it's "not a police problem") and there's no evidence that there has been an increase in recent years. Between 1976 and 1989, there was an average of 2 mass murders every month in the U.S. Again, there may be more recent data. -Mike Palij New York University [email protected] --- To make changes to your subscription contact: Bill Southerly ([email protected]) **************Hurry!
