Earlier today, Dan Murphy of the Christian Science Monitor tried to figure out how many rockets and mortars have been fired from Gaza into Israel between January 2012 and October 2012. “How many rockets were fired from Gaza at Israel this year?,” the title of his piece asked.
According to Murphy, he “distilled the numbers of mortar and
rocket attacks published by the Shin Bet in its monthly reports for
January-October.” Murphy claimed to have “triple checked”
the reports, which are easily accessible in English
and Hebrew.
So, what’s the problem?
In short, Murphy conflated the total number of attacks
(aka launchings) and the total number of rockets and mortars fired. If one does this (counts attacks rather than
rockets and mortars) then the amount of rockets and mortars fired from Gaza into Israel
will appear much lower than its true figure. It must be made clear that one
attack or launching can include multiple rockets and/or mortars.
Murphy should have known this, especially if he "triple checked,"
because the Shin Bet adds the following message in their PDF releases.
Below is a photo of Murphy’s original compiled data as well as a chart showing what he did wrong. I let Murphy know all of this
in a series of tweets. After challenging me, and then being pushed back, Murphy
decided to block me for “too much snark
and condescension.”
Interestingly, from the same tweet we see that
Murphy admitted that “perhaps” he had counted attacks rather than the total
number of rockets and mortars. Murphy has since updated (see photo below) his
piece (he gave credit to someone else for pointing out his error),
but the data is still incorrect in some places.

* There appears to be a discrepancy in some places with
regard to the amount fired in March. In some
places the Shin Bet puts the total at 208, however, in other
places the total is listed as 192.
** Neither Murphy nor myself count the rockets that
originated in the Sinai in April
*** As noted above, Murphy’s own data reaches a total of
723, however, his post says 552.
