Songs to deter illegal immigrants
The 3,000-kilometre US-Mexico border is the most frequently crossed
international land border in the world, with about 250 million crossings a year, some
of them legal, some not. Every year approximately a million Mexicans seek to
improve their fortunes by migrating illegally to the USA- and every year several
hundred lose their lives in the attempt. 1._______ People smugglers, known as
‘coyotes’, demand high fees and then abandon the migrants in the wilderness at the
first sign of danger. In some cases, being found and arrested by the US Border Patrol
may be a blessing.
Recently, the US government have come up with an innovative weapon
against illegal migration: poignant ballads with Spanish lyrics, describing the danger
of trying to cross the border. 2. __________ They belong to the traditional and highly
popular Mexican genre of ‘corridos’, narrative ballads whose lyrics may be love
stories or legends of famous heroes and criminals. The ‘ migracorridos’ tell tragic
tales of immigrants meeting with abuse and death on the dangerous journey. The
message: it is not worth it.
In one of the ballads, a singer called Abelardo sets out to cross the border with
his cousin Rafael. They manage to reach US territory, but are lost in the desert
without water.
3. ________ Later Abelardo wakes up to find his cousin dead by his side. In another
song, a group of friends are abandoned by a human trafficker, locked inside the trailer
in which they were being transported, where they slowly suffocate to death.
The US Border Patrol commissioned the migracorridos CD from a Hispanic
advertising agency based in Washington.
4. _______ The ballads appear to be popular, with listeners phoning in to ask for
more and wishing to find out about the singers.
5.________ The decrease could be due to a number of factors, such as more patrols,
better technology and fewer people trying to cross the border as a result of the
economic crisis in the USA. It is too early to estimate the impact of the migracorridos.
However, the creators of the campaign believe that if they have managed to get at
least some people to think twice before throwing themselves into the deadly risk, that
is already a success.
A A CD of such songs has been distributed free to radio stations in northern
Mexico.
B Because of the length of the border and the inhospitable nature of the terrain,
illegal migration is extremely difficult to stop.
C Official statistics show a drop in both arrests and deaths on the US-Mexican
border in 2008.
D Some die of thirst and exhaustion in the desert, some drown in the Rio Grande
or are killed in car accidents.
E After many hours of futile wandering, they lie down to rest.
F This fact has not been publicised, and sometimes radio DJs who play the songs
are not aware of their origin.
