More than a million people were fined by police during the spring [1]. So many fines, that we are still seeing news about judges taking decissions on these fines, so it clearly overloaded our justice system. Surprisingly, many of them are being rejected by judges because of not being fair.
Police officers can fine you if they believe you are infringing the law, and civils have to take their word as granted until a judge makes the final decission. People were fined in the spring for things such as driving to pick up groceries in a store different than the one closest to their homes [2], or because of walking the dog (one of the very few exceptions to leave the house) "too far from home", despite the law having never settled an official maximum distance [3].
