Explain why it is sometimes difficult to identity deviance?

Deviance is a violation of social norms. It is hard to detect deviance because not everyone is agreed on what is deviant behavior.

Explanation:

There are many spheres of behaviors that are considered as deviance, like crime, but behavior as riding a bike on the pedestrian side for some people is deviance and for some people is not.

Wherever you look, there are different norms.
