I've just realised I've written an essay on this... sorry! Was going to heavily edit but it might be interesting to someone so will leave it!
TL;DR - it's a national computer database. Each force has their own Intel database so it's covered on local and national level. There is no way across both levels we would miss a link between a former male offender, and a new 'woman' going around offending. We would not create a new record for the 'woman'... his old record would be updated (once arrested/had dealings with us).
We wouldn't be notified if someone changed their gender, only if they were previously known to us and then arrested after 'changing' - we'd then update our local database and their PNC record would be updated to include their new name - in very small circumstances maybe their main name entry would be changed but I don't think this is a policy yet.
Perhaps it will soon be...
If someone had offended as a man and then transitioned but never got into trouble with the police, I don't think we'd ever find out about it.
Do you know if different police forces have difference policies on this? Or is it a national database?
I have worked in two forces and as far as I know it is a national practise - the police national computer (totally national) is a bit unwieldy and you don't have a huge option to change any details once they're inputted, if any at all.
I've been trying to remember whether the PNC entry for this specific TiM was changed so their main name was altered. I seem to recall a big fuss because it was changed.
We don't usually change main PNC details so it was very unusual.
For example, if someone's name is spelled wrong on first arrest, any further dealings with police will be linked to that old name but perhaps an entry will be made to say an alias name is their correct name. But the initial entry itself won't be changed iirc.
So the idea that we would be able to go in and delete Male for Female and change names is improbable when we can't even do it for name errors, driving licence errors etc
The records themselves are usually detailed. Physical descriptions on each arrest are recorded: not just height/weight but hair style, tattoos, marks on body etc
And our 'career criminals' often have numerous aliases (including misspellings but also totally separate invented names)
So this TiM has a list of names I think including their 'deadname' and some other aliases they have used over time.
I should add that most forces have a separate database for their own crimes, investigations, intelligence etc (some forces use the same database and can view each other's data, but by no means all forces do this).
So even if someone hasn't been arrested but has had a complaint made about them, are victims, or witnesses, there should be an entry in their force Intel system.
Furthermore in my most recent force the local database was linked so a new identity would just go onto the person's main page. Their main screen probably would be altered to indicate new gender and names but their information and former dealings with us wouldn't be deleted. You can enter Notes so I'm sure this information would be included in the main screen.
I'm 99% sure we wouldn't just start a new entry for a TiM with whom we had had previous dealings.
that would be ridiculous and a step too far for most coppers! We are naturally suspicious and cynical (and probably conservative and old fashioned too).
My old force's database was similar.
Are the police routinely informed whenever someone gets a GRC or changes their name? And do you know whether the GRA is planning to change this?
No way, I don't think we're informed of anything like this.
But considering we only really have detailed dealings with offenders we'd only be interested in someone's gender change because of the practicalities - if they were arrested and we suddenly had to provide different detention officers to search the person/officers to watch, if required. (Our guidance is to ask the individual who they would like to have search them.)
