(AP) — “I think there’s a lot of blame to go around and spread around for decades,” said Mark Krikorian, executive director for the conservative Center For Immigration Studies. “There isn’t one person responsible.” Instead, he said, the problem lies in how the Immigration Control and Reform Act of 1986 was implemented. He described the passage of the bill as something of a “con-job” that allowed millions of immigrants in the country illegally to have legal status with a promise of workplace enforcement and other measures to curb future illegal immigration. But that didn’t happen, he said. And there was little incentive to follow through on promises of strict workplace enforcement, he said, once millions of people were legalized.
