> Are they defying the Spain government mandate?
Nobody has claimed that this is a government mandate, it isn't. It's a court order, coming from the judiciary. While Americans might consider the judiciary to be a branch of the government, in Spain it is considered entirely separate.
> Execute people on the spot, what the fuck are you even talking about?
The police will absolutely kill you if you try to forcefully resist them when they come to arrest you for violating a court order. This is not unique to Spain, but is more of a universal principle.
