Police and public health officials in Northern California are on the hunt for a man with tuberculosis who's refused treatment and could be contagious.

Last week, San Joaquin County prosecutors issued an arrest warrant for Eduardo Rosas Cruz, who went missing before completing treatment for the lung infection. He's also of particular concern to health officials because he's from a part of Mexico that's known for a drug-resistant strain of TB.

Law professor Erwin Chemerinsky, the founding dean of the University of California, Irvine School of Law, joins Take Two to discuss the legal issues that arise when a person refuses treatment for an illness that poses a public health threat.
