I have no idea how a prosecutor can take down these organized rings. The entire method prosecutors use for say exotic drugs, guns, etc: "Ok we have you for 5 years here, who do you work for, make these phone calls, we can get your sentence down to parole". This allows prosecutors to work their way up. But if a prosecutor is sitting in front of a low level shop lifter - who gets out that day - i don't see any prosecutor leverage.
And? US policy on handling shoplifters has not undergone any meaningful change in just the last couple years; I assume Europe has also largely maintained the status quo.
Mostly, except pretrial detention for minor crimes is unfortunately still not that uncommon in Europe.
The lack of bail often makes this worse, a weird obsession with “fairness” forces us to continue locking up people with sufficient assets to insure against absconding. Poor people can’t afford bail? Better make everyone else suffer too.
