@Cabochard I get that OP is remorseful but it doesn't change the fact that she committed a crime. I doubt very much that the police wouldn't record this as a caution as they need to keep a record as such should further instances happen.
The link I posted states that she wouldn't necessarily have to 'sign the caution' it's there in black & white.
It's ok you all telling her that it wasn't recorded on her police file, it's not you that would have to explain should be be questioned over not declaring it & therefore looking dishonest.
Like other posters said, she will no doubt be given the chance to explain, but come off it how many other people will also come up with a sob story in these circumstances which ultimately employers etc will be used to hearing all the time 🙄( I'm not saying OP's explanation re grief isn't true here by the way )... but it doesn't change the fact that she did what she did.
I hope that the university and more importantly future employers do take her seriously regarding her explanation but that can't be guaranteed.
If I was in OP's position I would for sure get a copy of her police record so she knows where she stands with it.
So I stand by what I said, which is unfortunately OP will have to learn from this & deal with the possible consequences of her actions however harsh that sounds.
OP just be thankful that it wasn't a much more serious crime & in future if you are thinking do irrationally that you aren't considering your actions please stay at home!
