... so we have 173 true positives, but 450 people were arrested.
I guess the 277 wrongfully arrested ones may have an opinion different from yours.
- mic47 8y agoThat assumes that both numbers are for the same period and that each arrest correspond to 1 match, which most likely will not be be true. For example if system identified only subset of people, but when you make arrest you arrest all. That means that now you have more arrest attributed to system, than number of matches. Since article does not do any attempt to answer these discrepancies, there is high chance the devil is in the details of definitions of those numbers.
- Silhouette 8y agoYou appear to be comparing two unrelated data points. The 92% and related figures were for one specific occasion. The 450 was total arrests since the technology was introduced. The article specifically reports the police saying no-one has been arrested as a result of an incorrect match.
