What makes you think the 96% number is per character as opposed to per plate?
Plates can have variable number of characters, which makes it nonsensical to define OCR accuracy per plate. So, OCR accuracy of 96% must be per character. Flock have not defined what they mean by OCR accuracy as far as I can find. In such case the standard per-character approach to calculating accuracy applies.

Yes I know, this is Slashdot and you are supposed to comment without reading the article. Well I did read the article and wouldn't you know it:
Jenkins began taking a more aggressive approach to prosecuting people accused of crimes. Meanwhile, the SFPD beefed up its tactics to fight car thefts and break-ins. In 2023, for example, the police increased patrols in tourist areas known for car break-ins and used "bait cars" to catch and build cases against organized car burglars.
The Flock cameras were not the only variable that changed. By the looks of it it isn't even the most significant variable. Nothing in the articles speaks of what each of the variables contributed to the final 11% reduction. All of the evidence is quotes of people with vested interest saying "Trust me bro, it is the cameras". Well in that case all I can say is "Trust me bro, it is the cops, the bait cars, and the aggressive prosecution"

According to flock's own press releases their OCR accuracy is 96%. This means that the accuracy of reading a six character plate number is ~78%. This is likely reflecting the best case scenario and not real life where lighting, dirt, motion, weird angles, and obstacles are all degrading the accuracy.
So besides the couple of criminals that they caught, can we please hear about all the people who got stopped, potentially arrested and perhaps even had guns drawn on them? Also are they saying that they would have never caught the criminals by other means if it wasn't for the Flock cameras.
Don't get me wrong, I see the value of these cameras for solving crime. I think this is undeniable. What is also undeniable is the misuse and the deleterious effect mass surveillance have on democracy. Unless there is an independent and transparent oversight system that ensures this data is used for the cime purposes being claimed I think it does more bad than good. "Trust me bro" is not going to cut it for me. What is also important is who is physically in possession of the primary data and its derivatives, and how is their use of the data ensured to be lawful. It doesn't seem that the local law enforcement olds the data.
