"McNeely, and his lawyers, argued that his Fourth Amendment rights were violated by taking the blood sample without his consent. The U.S. Supreme Court agreed that by not getting consent or obtaining a warrant from a judge, the blood test constituted an illegal search.
"...the natural dissipation of alcohol in the bloodstream does not constitute an exigency in every case sufficient to justify conducting a blood test without a warrant," Justice Sonia Sotomayor wrote for the court.
Missouri and the Obama administration were asking the Supreme Court to endorse a blanket rule that would have allowed the tests without a warrant."
Liberals everywhere say that nobama does not want to get rid of the second amendment; but here is proof that he wanted to get rid of the 4th Amendment. But just like his weapons bill chipping away at the 2nd Amendment, that was shot down by the democrat-controlled senate; the wisdom of the supreme court slapped obama after his attempt at pissing on the constitution again. Gets even better when the justice that is quoted is one nobama appointed!
