It always seems to follow the same script. First, there's a tragic event. Then there are mass protests around the country trying to affect some sort of change to prevent it from happening again. After a day or two of peaceful protests, violence, "rioting", and looting begin. Suddenly, the popular opinion begins to change, and the focus on the original event is lost. Over and over, people are saying "I support 'XYZ', but not the rioting and looting", which ends up becoming "why do they
have to riot and/or loot?" Over time, they
come to be seen as unworthy of sympathy.
It would be tragic if it wasn't so obvious.
