Rome, April 29 - One of two Italian policemen shot by a gunman on Sunday while Premier Enrico Letta's government was being sworn in risks being paralysed, according to medical reports. Giuseppe Giangrande, a 50-year-old member of the Carabinieri police force, suffered damage to his spinal cord after being shot in the neck. The other policemen suffered less serious leg injuries in the incident that took place near to the Italian House and the premier's office in central Rome. Prosecutors said Luigi Preiti, a 49-year-old from the southern town of Rosarno, wanted to shoot politicians he blamed for his personal plight, after the loss of his job and the breakdown of his marriage. He is thought to have planned the attack several weeks ago and to have worked alone. Nevertheless, the gesture has been interpreted as a sign of the desperation many in Italy are experiencing as the country struggles to cope with its longest recession in 20 years. Preiti is not thought to be suffering from mental illness, although media reports say he had a problem with gambling on video-poker slot machines.
