The vast majority of prosecutors are the scum of the earth.
Most of today's politicians of both parties are scum -- the muckraking of the media have insured that few but dirty-handed sharks with rackets backing them up can survive.
Our freedoms have been corrupted by the huge distances people can now travel, both by care and plane, and also due to television and cyberspace. Nobody really knows anybody anymore, and hence accountability is way down -- it's all spin. But today's solutions (computerized methods of tracking people) truly are tyrannical, because they have no forgiveness and can't make the judgment calls that the local cops used to make with individuals.
And it will only get worse, people.
