I'm just reading through things here, and I'm wondering if, during the course of an investigation, a potential suspect is looked at by LE, and found to have an iron clad alibi, and/or other information comes to light absolving that potential person of any responsibility for the crime at hand, would LE continue to investigate that individual in relation to the crime being investigated?
And then, there's this idea that, should a particular avenue of investigation prove to be in error, either by further evidence coming to light, or by legal testimony to the fact that avenue of investigation was in error, would LE continue to investigate that avenue in relation to the crime being investigated?
