It's usually because a driver turning (right) on green doesn't have to worry about merging into traffic, so they only need to focus on pedestrians. Hopefully they will. A driver turning right on red has traffic coming from their left and pedestrians walking in front, and they're usually more concerned about the cars, so they tend to look left while turning right. Ouch. It's a growing issue as well because of the growing size of cars. Littler people can be completely concealed behind a front grille.
A car turning left on green is also an issue because while they should be able to see and wait for pedestrians, they're often occluded by other cars and trucks, and those left turners can be in a hurry to proceed through a gap in traffic.
Also, while technically a right on red should require one to come to a full stop, then start their turn, in practice many people are doing rights on red at rolling stops at significantly higher speeds.
