What Does the Ariz. Immigration Verdict Mean?

U.S. District Judge Susan Bolton struck down every section the Obama administration cared about: a complete victory says CBS News chief legal correspondent Jan Crawford.

So this now puts the pressure on the federal government -- and the White House -- to take responsibility and do something to fix immigration.

But the fight in the states isn't over. Twenty states are now considering similar laws…and this is just one judge's ruling. full story

美國聯邦法官蘇珊·波爾頓下令禁止亞利桑那州執行頗具爭議的移民法中的主要部分。原定周四（7月29日）在亞利桑那州生效的新法律規定警方可以在沒有逮捕令的情況下，以「合理的懷疑」而逮捕並且拘留疑似非法移民的人。

雖然這項判決被視為民權鬥爭的一項勝利，但是仍有二十個州正在考量類似的移民法。與此同時，聯邦政府在修補移民法方面，也將面對更大的責任和壓力。

Most Americans Worry About Safety Of Food Supply

Government officials have said for years that the U.S. has the safest food supply in the world. But recent events aren't doing much to inspire confidence in that mantra.

According to a national survey conducted for NPR by Thomson Reuters and released today, 61 percent are concerned about contamination of the food supply. Most of them — 51 percent — worry most about meat.

That doesn't stop us from consuming about 63 pounds of beef per person per year, mind you. But meat safety is a big concern compared with the 25 percent of people who worry most about seafood and the 23 percent who fret most about produce. Dairy got a pretty low 4 percent response. full story

雖然政府一再強調美國的食品安全冠居全球，但是最新民調結果顯示，61%受訪者對食品污染表示關注，其中51%最擔心肉類安全問題。即使如此，美國人平均每人每年吃下63磅牛肉。另外有25%受訪者對海鮮安全感到擔憂，乳製品相對只佔4%。

Growing outbreaks of whooping cough — including a California epidemic that has killed six babies — are worrying public health officials who fear that sporadic vaccination practices may be contributing to dangerous cases of the preventable disease.

Rising cases of the disease also known as pertussis have been reported in Idaho, Texas, South Carolina, Michigan and in California, where 1,500 children have been diagnosed in what's being called the worst outbreak in 50 years. full story
