Probably the one scandal that perhaps epitomises British society today, in which literally hundreds of people were convicted of financial crimes because post office software was shit, and no-one is going to be punished for it. This has been going on now since the 90s, and prosecutions continued until 2015.

Nobody appears to have known what was going on, but they knew enough to say no-one else was having problems, and that if money was missing, they were going to be prosecuted for theft.
