It will depend on how the media spin it. Naming the victims is not customary, providing their home addresses or any personal info - even less so. I don’t think people will get blamed for getting sick; nor should they. At the same time, public health officials will have to quarantine everybody in contact with the infected people, so the responsibility will be really on them, not on the homeless population. Here we finish the full circle and come back to the fact that municipalities do not have adequate facilities to quarantine a large number of people. They don’t have the authority to preventively arrest and jail people who did not commit any crime either. This is America, after all, not the late USSR.
