I realise this already has a lot of responses, however I've had a quick skim and thought I'd say my part.
I feel you've made some valid points, however have provided no valid fixes for this issue, from what I can see.
"Why are we allowing Police to not identify the owner and user of a vehicle".
"Why are Police relying on a fundamentally faulty system"
To your first point, I would like to ask you if you have spoken to the user who stole your vehicle?. If so, please inform us as to what information they provided to the Police, as a lot of this is what goes into the decision making process. Now, you say that when Police check the reg and see Mr. Chee, not a [R3kT] gangman, can you confirm where the Police are getting the information that the user is indeed [R3kT] gangman and not Mr. Chee?. Are you insinuating Police should metagame, or are you certain that the user provided a name different to that of the owner of the vehicle. Again, this is a lot easier for us to look into and see if Police were in breach of good practice if we can know what they were told.
As for the faulty system, I would ask what your recommendations are as to what the Police can rely on that can be used now?. The dispatch system is the best chance you've got, at alerting the majority of Police Officers on duty that your vehicle has been taken. This is your property, the onus is on you to protect it and ensure it is kept safe and you are aware of where it is at all times.
Regarding the breach of good practice in the Police Force. I feel that if you are using that term to blanket over the whole process, then you are wrong and I would disagree as it is currently the most professional and efficient system we have for scrapping vehicles.
Regarding your statement later on that Officers scrapped your vehicle in the full knowledge that the owner was not involved and associated with the crime, then this is indeed concerning and I can understand your annoyance. I would imagine that Police Command are investigating this.
Regarding your example about your Ford being stolen. I would ask you to respect the fact this is AltisLife and we cannot uphold the Police standards set in real life. We cannot fingerprint, as that is seen as powergaming, we cannot dispute licenses, as that is seen as powergaming / metagaming, we have no means of identifying a person other than the information that person gives us, because of rules and limitations presented by the game.
