Robert found no job of his liking, so he joined a goon squad and became one of the worst goons.
It’s common knowledge that goons are patronised by politicians and businessmen and protected by corrupt law enforcement officials.
There are goons of every type: religious goons who beat up others in the name of god, political goons who beat up, suppress or even kill members of opposition parties, corporate goons who threaten and control other businesses and, of course, the good old ‘street or local goons’ of an area who bully and threat the residents and live on the money they get from extortion.
