应该如何对待罪犯
1．criminals 应该be locked up in prison(jails)．
2．can ensure a safe and comfortable living environment for law-abiding citizens．Thieves ,robbers, rapists and murders are dangerous, pose potential threat to the society
3．放到监狱教育是一个很好的方式，让他们知道侵犯其他人的权利是要付出代价的，这样就会减少他们再次犯罪的可能性
4．不但是punish criminals but also deters the potential criminals．有些有犯罪倾向的人由于害怕被处罚，可能会放弃commit crime．
5．应该放到监狱。Just as the old saying goes, mercy to the criminal may be cruelty to the people．
