Medical quarantine has been necessary and beneficial in the past. You have a point regarding implementation of such a thing by a government prone to politicizing everything and punishing political enemies, I’ll grant you that much. But, that does not change physical reality or remove the necessity of halting the spread of disease.
The aftermath of 9/11 gave us the Patriot Act.
With the Ebola panic, don’t give Obama or the next president to power to quarantine citizens.
