Air safety is a beautiful example. Commercial air travel is impossibly safe considering the complex machinery and systems. Note that of four commercial disasters in the last two years, three were deliberate human acts.No I do not. If there are systemic problems this affects many people. I think that many of the people criticised here, probably did what they usually did. They did not behave any worse in this case than others. Picking on individuals in one case will not prevent the same bad things happening again.
For instance, I previously referenced another case where the postal police wiped hard drives when trying to read them. In the Elisa Clasps case Pascali criticised Steffanoni for not following protocols. I suspect that Steffanoni was doing LCN testing without the facilities in that case also. It would be interesting to know what training judges underwent in the evaluation of genetic evidence so they can ask the right questions to ensure the testing was done appropriately. England has an external regulator and standard setter for forensic science.
So if one wants things to improve, focussing on individuals is not the answer, one needs a systems approach as happens in air safety. Individuals make errors, you put systems in place to reduce those. E.g. Record interrogations. Investigate allegations of police misbehaviour. Ensure laboratories have QA systems in place and external validation. Forensic errors should be reviewed - why were the shoe print rings miscounted, were the 'experts' doing this trained in analysing shoe prints. Did they have SOPs in place? Were measures done blind to the reference prints?
These judicial systems should be as accurate as air safety, but there are excuses made that make no sense.
