The harmful effects of law enforcement tunnel vision do not end with wrongful convictions. Tunnel vision also undermines community trust in the police and damages an already fraught relationship.
In a sexual assault case, real victims are actually harmed when false allegations are buttressed by so-called “victim-centric” investigations. When false reports are “substantiated” others watching become cynical about sexual assault allegations in general. When people do not trust the system and the witnesses produced then it becomes likely they will apply a bias against sexual assault victims.
