The thing is,gypsies are mostly into professional begging,stealing,scams,scavenging,drug trade(mostly weed) and gang fights.
They are notorious in the Balkans for that. Now we're not talking about all of them,but most of them.
They are probably the hardest people to assimilate.
Now supposedly,the gypsies in Ukraine,where scamming or looting,that's why you see Ukrainian militias abusing them in various videos. I don't know what's the story with the video,but Ukrainians usually blame them for looting while the country is at war.
