It was a despicable crime. It ended a life full of promise, a senseless and tragic loss. It reflected all of our fears - a young woman traveling alone, her car breaking down, leaving her at the side of the road, vulnerable and frightened. And it struck terror in the hearts of all parents, watching their twenty somethings navigate in an inhospitable world. The perpetrator deserved to be caught, tried and punished severely. But the murder of Melissa Gosule - horrible as it was - cannot justify the “Three Strikes and You’re Out’’ bill, currently pending in the legislature. “Melissa’s bill,’’ as it has been called, is supposedly aimed at keeping the most dangerous repeat offenders behind bars, without the possibility of parole. Its backers insist that this bill is designed only for the predators, the worst of the worst, the “habitually violent offenders,’’ presumably, like Michael Gentile, the man convicted of Melissa’s murder.
