The quote from Carl Hiaasen's book "Native Tongue" describes the deceased as a notorious troublemaker or troublemaker ("scumbucket") who was unlikely to take their own life. Instead, the narrative suggests that it is more common for someone else to be responsible for such actions.
This statement highlights a cynical view of the individual's reputation and hints at the darker, more complex context surrounding their death, implying that their demise might have involved third-party influence or circumstances rather than self-inflicted harm.
