refers to when people feel cast out of society and as though they do not belong or have a place
marginalised groups lack both clear goals and organisations to represent their interests.
e.g homeless, ethnic minorities, unemployed youths
unemployed youth are marginalised - no organisation to represent them and no clear goals - have a sense of frustration and resentment therefore crime is used to express the frustrations
e.g subcultures, violent crimes, riots, vandalism
