She had symptoms when she arrived in Newark. She had a fever, came in from West Africa, and had worked with patients who had Ebola. It wasn’t just any tent. It was a nicely accommodated mobile hospital room in a special isolation tent.
Once she tested negative for the virus, I agree that she was free to go to self monitored quarantine.
Just because she has now raised a ruckus about this, doesn’t mean we shouldn’t proceed with caution when the situation warrants it, as it did WHEN she arrived in the States.
Besides which, heroes don't usually whine about situations that inconvenience them.
