It feels like Good Samaritan laws have gone in and out of favor over time in America. For many years after 9/11, no able-bodied man boarded an airplane without first preparing himself to tackle a terrorist if he had to. Does that happen anymore? Or would the passengers laugh and whip out their phones as the terrorist slit a flight attendant’s throat? You will not go to jail for watching someone beat another person to death as you stream it live on social media. That’s perfectly acceptable now, even encouraged.
