No, there’s no scientific backing to really confidently say that no two fingerprints are alike. That doesn’t change that we can identify them and match them.
If you observe that fingerprints can be matched, that’s all you need to know.
Meh, they do work. They just measure stress response, not truthfulness. The idea being that you’ll have a heightened stress response to a question you are lying about the answer to, which may or may not be accurate depending on individual and situation.
So they don’t work. They’re nothing more than pseudo-science gobbled up by “Truth, Justice, And The American Way” boomers who also watch NCIS and cheer when they blow up the bad guys on the big screen.
Breath analyzers aren’t exactly accurate. There’s a bunch of things that can give them false positives, they often aren’t properly calibrated, and the science behind them is kinda shaky. They got challenged often enough in certain states that in at least one state if an officer has you breathe in a machine and that machine produces a number higher than the legal BAC limit, that’s proof of DUI regardless of what the machine may or may not do to result in that number.
Fun fact there is literally no scientific backing to field sobriety tests. In fact there is a lot of scientific evidence proving they don’t work.
Pigs are liars?
Gasp.
That’s interesting. Any recommended ones? If I had to guess its a lot easier to find flaws in something than it is to prove it 100% right.
As I understand it, these tests are trying to get more data on if the driver is severely intoxicated or has major motor function issues.
Or fingerprints, or lie detectors…
There’s no scientific backing to fingerprints? Whaat

Now lie detectors don’t work at all…

Yeah, why not use a breath analyzer or something. I am a drunk and could do those test really wasted.
Because it’s harder for cops to discriminate against dark skinned people if they use objective measurements.

You can always take your chances on a blood test…
