Opponents have jumped on the protocol for potentially shooting down unresponsive planes, saying it amounts to a death sentence. But Security Secretary Eugenio Burzaco said yesterday that would only be a last resort.New President Mauricio Macri has vowed to crack down on drug trafficking and Burzaco says there were some 400 irregular flights into the country last year.The fatal shoot-down of a missionary plane in Peru in 2001 led that country to suspend a similar policy until last year.
