Leland Yee, Assistant President pro Tempore of the California State Senate, introduced SB399 this session. “Children have a greater capacity for rehabilitation than adults,” said Senator Yee, who is also a child psychologist. “The neuroscience is clear; brain maturation continues well through adolescence and thus impulse control, planning, and critical thinking skills are still not yet fully developed. SB 399 reflects that science and provides the opportunity for compassion and rehabilitation that we should exercise with minors.”
