Matza evaluated functional subcultural Functionalism Marxism( functional subcultural, Functionalism, Marxism ) theory and came up with the main concepts of moral panic subterranean values focal concerns( moral panic, subterranean values, focal concerns ) drift and techniques of neutralisation adjustment justification( neutralisation, adjustment, justification ) He argued that people that commit crimes are still a part of society because people just float slip drift( float, slip, drift ) in and out of deviance, so when people are younger they may be more deviant than when they're older. Matza argued that we all are deviant and it's called our subterranean values that go off at the wrong time in the wrong place that make us commit crime. However, he says that people commit crime and then use techniques of neutralisation to justify their actions get away with the crime to make themselves feel better( justify their actions, get away with the crime, to make themselves feel better )
