Culprits

Who were the culprits?

Now they will say that they've found the culprits.

The primary culprits in eutrophication appear to be excess nitrogen and phosphorus—from sources including fertilizer runoff and septic system effluent to atmospheric fallout from burning fossil fuels—which enter waterbodies and fuel the overgrowth of algae, which, in turn, reduces water quality and degrades estuarine and coastal ecosystems.

No matter what they've done, I don't think we should name and shame the culprits.

They didn't find the real culprits.

Dmitri was the main culprits.

During the Big Scare, while everyone was afraid that the Exclusion Ultimatum meant the Martians wanted an interplanetary war, the Earth Governments would have been only too ready to hang, shoot, stab, gas, electrocute, freeze, burn, poison, impale and/or defenestrate the dastardly culprits responsible.
