Spectaculair colorized version of Altgens' famous photo, courtesy of Robin Unger. The secret service agents looking over their shoulder, where a 'firecracker'-like sound was heard. Kennedy can be discerned, lifting up his arms as a response to being hit. After staring at this photo for a while, I felt both thrilled and very sad. This moment ... all moments change everything, but this one feels like when history made a turn into darkness.
