Wrong. The other side reneged on the agreement.
The Rochas have a key and free access to the house in the absence of Laci and SP per prior agreements with them. No legal action was taken by Petersons to secure the property from entry by the Rochas. The proper legal thing to do for the Petersons was to get a court order barring the Rochas and have it legally served and a hearing held. The Petersons were never legally in complete control of the house and the Rochas were never legally barred from entering.
The Rochas had tried to cooperate with the Petersons but the the Petersons attempted to exercise unfounded control. Rochas put it to the test, nothing underhanded here. No midnight burglary, it was broad daylight with media thick as flies recording the whole thing.
The items taken for safe keeping were cataloged and that inventory was given to the police officer on the scene. Hardly theft.
