For example, if a cop says "I'm pulling this person over because they have a busted tail light", it's hard for them to make a claim that they thought the person could have been some sort of drug kingpin that needed further searching.". Compare this to "I'm pulling this vehicle over because I just saw it leave a known drug house."
The more we can recreate "presence" at a particular time and place when a crime (by an individual or by a LEO), the more information judges and juries will have to deliberate if suspicion was in fact reasonable, and not based on some arbitrary detail like the race of the person being stopped.
Recreating presence makes it so someone no longer has to depend on top-notch legal council to artfully argue why they are innocent. It should bring down the legal costs of both the prosecution and the defense, while achieving greater justice.
Of course, the only time that kind of stuff gets vigorously challenged is if the defendant has top-notch legal representation. Public defender's typically would rather just plea-bargain it out.
Still, it's great progress for keeping everything above board as much as possible.
