Barry McCaffrey also touted eight Xray machines the United States is deploying on the U.S.Mexico border, saying their ability to spot drugs in trucks will push traffickers elsewhere to sea or air shipments and reduce border violence. But law enforcement crackdowns in foreign countries and careful border searches won't cure America's drug ills or the violence the illicit trade spawns here and abroad, he said. "Our principal contribution, without any question, will be to focus on 68 million American children, between the ages of 10 and about 19, and try and get them to not smoke pot, abuse alcohol or smoke cigarettes," McCaffrey told reporters yesterday. If youngsters can grow up without doing those things, "they won't create the next generation of drugabusing Americans."
