If they genuinely thought the dog was drugged, then they would have to prove it. It's not exactly difficult if they know what to look for. They could take pictures, videos, a witness if possible, and submit a sample for testing. Sure the latter would cost money, but it sure as hell would've made them look like the good guys if the evidence added up (considering this could be a very serious offense). But all we see is a group of people ripping a dog from the man, puppy is screaming and struggling, and those people sticking the up dog for sale with the name "Vegan" as a statement. If they thought this wouldn't be seen as shady and hateful, then their heads are up their asses. Well intentioned vigilanteism or not, until we see more confirmed details, this group seems to be in the wrong (and it wouldn't be the first time a person stole a dog that didn't need help). If there was a genuine concern for the dog's safety, then they should've reported it to the proper authorities who would've likely handled it MUCH better (maybe creating a report so we wouldn't have so many rumors). I'm Canadian, so my knowledge on the Roma is somewhat limited, but until something more concrete turns up, that's where I stand.
