Immigration in America would take a disastrous course if the 'enforcement only' crowd kept getting its way. And Americans would have to suffer for it.
"Last year, the federal government filed more charges for immigration violations than all other crimes and misdemeanors combined -- it charged more people for breaking our immigration laws than it charged drug traffickers, bank robbers, counterfeiters and everything else under the sun. Yet right-wing lawmakers and pundits who oppose a comprehensive re-think of our immigration system continue to insist the opposite is true: that the government is just sitting on its hands."
