Step-by-step explanation:
Fines are ineffective as legal punishment by a court of law for crime or other related offences because they are mostly use for minor crime and violation while most serious crimes offenders are punished by imprisonment by the court of law.
Fines are just a more lenient form of punishment than prison, and cannot deter those who commit more serious crimes that why they are ineffective as a legal punishment.
Therefore fines is an inadequate response to violent crimes. It can also give people a financial incentive to frame other people for crimes they didn't commit.
