Do you think the Three Strikes Law is an effective crime deterrent? Why or why not? I will like to argue that even though it has some effective qualities, it is still ineffective in stopping violent crime. 1 reason - The threat of a life sentence is not going to stop people who are act impulsively, without thought to the likely consequences of their actions Another reason -will disproportionately impact minority offenders More elaboration and more reasons are needed.
