A few will change. Over time most will go back to their norm. How many changed or learned after the clinton gun ban? 9/11, Y2k, hurricane Katrina, Chernobyl, etc. Most forget over time. Maybe a few government changes to make people feel good in the short term. OTOH, if this turns out to be a major catastrophe with a lot of people dead, a few more people will change. Just my 2 cents.
