Will they start kicking in doors to confiscate the ‘illegal’ weapons?
Maybe in one or two high-profile cases, "pour encourager les autres". And they will have reporters standing by to film the drama.
For the high volumes they expect later, they will just levy huge unpayable fines, shut off your bank accounts, get you fired, and reduce you and your family to destitution. You can appeal, but the legal fees will bankrupt you even if you "win".
I do not believe this conflict will solved in the courts or by elections. It may not go as well as the sponsors hope either. The opposition always has a say in the outcome.
