> What if law enforcement were required to "pay per search" a la PACER or journal subscriptions?

My immediate reaction is that it changes the nature of the surveillance enough to require further reflection. It would put a time-bounded window on the ability of law enforcement to abuse the data (albeit assuming the ALPR companies actually removing data per their stated policies).

I appreciate your comment, for sure. I'll have to ruminate on it and see how it meshes with my more-strongly-held-than-I'd-like reactionary (and probably not well thought out) beliefs. >smile<
