I suppose the difference is that in most other places in the world there would be no 'costs stemming from a false arrest' (I mean direct costs if you exclude things like the opportunity cost of lost time, and the damages/stress inflicted, etc).
In Germany you are compensated for a wrong arrest. (Base rate is 25€ per day, which isn't much, but you can claim additional reimbursements with some paperwork and help from your (state paid) lawyer)
