Witness protection is of the utmost

In common use in other countries, this device is a one-way tinted glass so that suspects cannot see their accusers in situations where eye contact can be an unnerving experience for victims. The inventors of the glass had one thing in mind, and that was that coming face to face with suspects -some of them charged with heinous crimes - could put victims or witnesses in more danger.  Society had learnt from ample experience, as many had been followed with deadly effect in order that the evidence against the alleged felon was eliminated. Many criminals  - hardened recidivists, some of them – thought nothing of zapping witnesses, or arranging for such a ghastly purpose, in order to secure their underserved freedom.  This is secondary victimisation on survivors who have to come face to face with their vicious attackers, in many instances rapists and armed robbers.
