It’s highly unlikely that if they were caught with explosives and hard evidence of links to a hostile state that they would have been granted bail.

The balance of probabilities says that they were just stealing diesel from nearby farmland.

Maybe they were just out there about to do a medieval larping party or something. Probably had vans full of pool noodles and foam shields and shit

Well thanks to the war, fuel is very expensive, and farms often have big bowsers of diesel on site and typically have quite poor security. This makes them a very attractive target for thefts. The odds are this is a gang of thieves that have been targeting farms and stealing diesel. Probably why the van was reported to contain explosive material- I.e. fuel. (Not that diesel is explosive per se but whatever). And these clueless thieves probably weren’t aware they were trying to do crime right next to the apparatus of the security state and definitely wouldn’t have expected to be set upon by a huge anti terror force.
