My view on this is that we're not going back and it would be silly to try to do so. Once you have the technology to record, track, and ultimately apprehend criminals, simply not doing so in the name of ideological purity becomes increasingly obscene. What we need are courts that understand the technology, prosecutors who fear censure for overreach, and fair laws about standards of access to the data.
It's here to stay. We just need good rules around its use. The benefits are too compelling.
