I understand the S Carolina police have turned on this guy since there is further evidence that he has committed crimes of this nature in the past and is a true murdering racist.
A dominican translator would have helped that interview quite a bit.
His newness to South Carolina and the typical way life functions in Charleston plus his ability to surmise the situation quickly could very well have saved the life of this witness.
