This is why we need to have already had the borders closed.

"A swarm of federal immigration agents sped silently, headlights off, down a Boston side street early Wednesday and surrounded an apartment house.

"Police! Policia! Police!" yelled Daniel Monico, a deportation officer, holding his badge to a window where someone had pulled back the curtain. "Open the door!"

Moments later, agents led a dazed-looking Jose Ferreira Da Silva, 35, out in handcuffs. The Brazilian had been arrested in 2002 and deported, but had slipped back into the country. He now faces up to 20 years in prison.

In a blitz that began May 26, U.S. Immigration and Customs Enforcement has arrested nearly 2,100 illegal immigrants across the country. Officials said the raids are aimed at child molesters, gang members and other violent criminals, as well as people like Da Silva who sneaked back into the country after a judge threw them out.

The crackdown is called Operation Return to Sender. "
