I would agree except that is clearly sticking the camel's nose under the tent.
They would require then that ALL sex offenders be microchipped and sex offenses could be expanded to cover taking a leak in a bush off the freeway (indecent exposure). Not to mention, the less than honest law enforcement officers who swear they saw you yanking your crank by a school and if you didn't, yet are found guilty by way of thier "irrefutable testimony", are chipped for life.
In other words, it would allow for them to acheive their goal anyway = microchip everyone eventually.
I say we microwave the perps.
