In divided ruling handed down today, the U.S. Supreme Court held that Missouri police violated the 4th Amendment by obtaining a warrantless and nonconsensual blood sample from a man suspected of drunk driving. At issue in Missouri v. McNeely was the question of whether or not the rapid diminishment of alcohol in a suspect’s bloodstream should entitle the police to enjoy a blanket emergency exception to the 4th Amendment when it comes to seeking blood tests in drunk-driving cases.
Ugh, cops giving roadside blood tests. Even aside from the huge privacy issues, that’s frightening on a practical level. They’re not exactly medical professionals.
