Unfortunately, I haven't really been able to find the statistics
you're looking for. It's a little tricky to search for information
about injuries from bullets fired into the air. Almost all of the
search terms you can think of using have enough unrelated meanings
that it's hard to focus in on relevant information! With a little
perseverance, I finally found a useful trick: look for the cluster of
words "fired straight up" plus "injuries."
I was able to confirm that people are often injured and killed by
bullets returning to earth from being fired straight up. Obviously,
the problem becomes much more serious in crowds. You can find both
forensic references (how to identify such injuries) and physics
explanation. For example, Dr. Karl S. Kruszelnicki discusses the issue
on his website at the Australian Broadcasting Corporation:
http://www.abc.net.au/science/k2/homework/s95523.htm
He calculates that a bullet fired at a muzzle velocity of about 3000
kph will return to earth at a terminal velocity of 330-770 kph, more
than sufficient to penetrate a skull, even if it is a lot slower than
the speed of a bullet fired straight at a person. (You only need about
220 kph to penetrate.) He further reports that "most people who have
been hit by bullets falling out of the sky get hit on their upper
back, the top of their head, or their shoulders." Injuries have
occurred from falling bullets all over the world. Karl reports that
"in Kuwait after the end of the Gulf War, the Kuwaitis celebrated by
firing weapons into the air -- and 20 Kuwaitis died from falling
bullets. In Los Angeles, between the years 1985 - 1992, doctors at the
King/Drew Medical Center treated some 118 people for random
falling-bullet injuries. 38 of them died. Practically all of the
injuries were due to happy holiday weekend revelers."

However, your real question about statistics for demonstrations in the
Middle East does not seem to yield to any search that I've tried,
either on the web in general or on news archive sites. It's easy
enough to find individual reports of injuries in a particular
demonstration, but if anyone has collected statistics for any regions
or time periods, I haven't been able to find them. The Middle East
does not yet have the same mania for the gathering of statistics that,
say, U.S. public health officials have.
I hope that this information at least partly satisfies your curiosity. |
