"The connection between serial killings and bad economic times is not definitive but there are indications of it: all of these the killers struck during a period of extreme economic uncertainty in German history"

It means that as an economic go down, people tend to be violent because they feel are angry . People  will always expect things to get better , to offer a better life for their family. Violent occur because some people don't know how to adjust to change, so when something unexpected happened, it might push people to react negative
I chose  this piece because when some  people are angry, they take justice in their own hand. And that put others in a place to fight back so they can get what they want..
