In any significant capacity? No. Because we'd see it in crime stats; the widespread successful use of license plate scanners should show up in a chart. The world before and the world after their introduction appears very similar from a crime rate standpoint; it stands to reason getting rid of them would be similarly low-impact.
I really don't think that'd be the same if we got rid of encryption tomorrow.
>In any significant capacity?
Notice the subtle shifting of the goalposts. Who said anything about "significant capacity"? The original argument was "it helps save actual lives". Now we need to see "widespread successful use" in the "crime stats"? How would that even be possible? These systems can't be implemented in a vacuum and crime stats are constantly fluctuating for countless reasons, so how could the specific cause ever be isolated? Yet crime has generally been on a downward trend for decades, can we be sure these type of systems aren't responsible for some piece of that?

Once again, why aren't you asking "Is there evidence in that direction?" You are demanding evidence for one and the other is just a hypothetical based of what you "think" might happen. But what is that thought based on? Do crime stats show that identity theft has gone done since the popularization of online banking
You are not treating these issues with the same rigor. Can't you recognize that?
