The claim that laws should be flexible enough to take account of various circumstances, times, and places evokes some discussion recently.Since law is a standard and a kind of criterion that opening to everyone, some advocates that it should not be changed even under the most dangerous circumstances.I agree with such an opinion that when a law is generated which means an agreement on a certain issue has been reached, then it should not be inflexible to everyone and under any situation.However, when this standard is producing, it should take accont of as more circumsstances as possible. Some says that law is a program that restrict people's behavior rather than a criterion that judge people's behavior.Circumstances is various, and changes unpredictable,thus, a law is only available to ensure the "righteousness in procedure", but not the "righteousness in moral".As we all know, the famous "simpson case" is a prototype that when all the evidences indicated that simpson will undoubtfully be the killer, his lawyer found a crucial mistake in that evidence-chain that the judge had to release him.Although almost everyone believes that he is the one, the law has to accord to its programs and rules.In another word, if the judge can give the laweven  a little flexibility by the will of the people, the law would not be available anymore.Thus, the law has to be recret when it is made use of. Nevertheless, a law is far more flexible in proportion to be made.It has to consider almost every situation by which to make the law considerable available and reasonable.For instance, the suffarage of women was a definitely new issue at that time and the institution has to account for this new trend.Furthermore, there has always been emergencies that a law can not sustain such as a sudden war.In the world war II, president Roosevelt changed the law of independence in time when America was assaulted by Japan, by which American can fight for their countries legally.Moreover, as the development of the modern society,it displays a divergence of new problems, especially when technology is improving in a remarkable accelerating.Apparently, new laws are called for to handle these problems. In conclusion, a law is a standard that restrict everyone's behavior and a program that no one can break.To account for more cincumstances, it has to be well-considered when it is producing, but once it is generated, it should not remain any flexibility.
