Training could remove racial bias from police reactions
...ence finds that extensive training with a computer simulation
where the race of a suspect is unrelated to the presence of a weapon can eliminate racial bias. Fifty police officers from Florida with two to thirty years of experience participated in one hundred and sixty test trials. The earlier trials revealed...
Researchers model brain's electrical storm during a seizure
