Measuring the arms flow from the US to
Mexico
The US is not the source for more than 90% of the
firearms seized from criminals by the Mexican authorities. That, at least, is
the message the US gun lobby has been pressing since March, when the US Bureau
of Alcohol, Tobacco, Firearms and Explosives (ATF) appeared to confirm the claim
the Mexican government had been making for some time, and even more since
President Barack Obama echoed it. The gun lobby is right to the extent that the
claim has never been proven — but overlooks the fact that it has
not been disproven, and that a
more precise determination of how many arms do come from the
US is becoming increasingly probable.
The ATF had not, in effect, confirmed the Mexican claim.
What had been said by an ATF special agent, William Newell, in testimony to the
House of Representatives Committee on Appropriations, Subcommittee on
Commerce, Justice, Science and Related Agencies on 24 March, was that '90% of
the
firearms recovered in Mexico, and which
are then successfully traced, were determined to have originated from various
sources within the continental US.'
The qualifying phrase is all-important: the 90% does not
refer to all firearms seized in
Mexico, or even to all those
which Mexico asked the ATF to trace, but only to those
which had been successfully traced.
More precise information obtained from the ATF by
FactCheck.org in April revealed that 10,347 firearms
seized in FY2007 and FY2008 had
been traced to the US, representing 95% and 93%, respectively, of
the firearms submitted for tracing.
Mexican submissions for tracing have been increasing
rapidly: 3,312 in FY2007, 7,743 in FY2008 and 7,500 in the first half of FY2009.
This reflects an even sharper increase in the number of weapons the Mexican
authorities have been seizing. It is not easy to make sense of Mexican tallies.
The federal chief prosecutor's office, the PGR, has reported a total of 35,943
firearms seized since President Felipe Calderón took
office in December 2006: 9,972 to
the end of 2007, 20,915 in 2008 and 5,056 in the
first three months of 2009.
The defence ministry (Sedena), has reported
army seizures of 30,576 firearms since
December 2006: 5,174 to end-2007, 14,774 in 2008 and 10,628 in
the first half of 2009.
Sedena, however, claims that its total of 30,576 is
equivalent to 53.6% of total seizures by all agencies, which would put that
overall total just above 57,000. This is hard to reconcile with the PGR data,
but both sets of figures do show parallel upward trends. By
all accounts, data sharing with the
US, including use of the eTrace system to determine provenance, is
on a similar rising curve.
Apart from the difficulty of reconciling Mexican
statistics that use varying timeframes (they are not published regularly but
tend to surface in response to congressional or freedom-of-information
requests), there is the added difficulty that Mexican agencies mix calendar
years with totals during a sexenio (the six-year presidential term) which adds
one month to the first calendar year and subtracts one from the last. This, of
course, does not match the US custom of using the October-September fiscal year
as the most common frame of reference for data. Harmonising data collection and
presentation is one of the tasks the two countries' law-enforcement
establishments have set themselves.
