John Evander Couey, the man arrested in the murder of third-grader Jessica Lunsford, was a registered sex offender who spent just two years in prison after a burglary conviction. Why are we so willing to make examples of the Martha Stewarts of the world, but so unwilling to keep sickos such as Couey behind bars where they belong? Sex offenders have a very poor track record of being able to overcome their deadly criminal addictions. Registering them is not enough. For the protection of our innocent sons and daughters, we must lock up people like Couey and throw away the key.
