The broken windows theory is a theory of criminology. So the statement is FALSE
Explanation
The broken windows theory argues that in a neighborhood where crime is seen as normal and is increasingly prevalent the breeding of criminals becomes much easier. Like in a house with a broken window, breaking in is easier unless that house if fixed by the people living in the house themselves.
It does not however justify allowing such a neighborhood to be on its own but merely discuss a phenomena that exists in such places.
