No, using illegally obtained evidence in court should not be allowed. In my opinion, the rule of law must be obeyed in prosecution of criminal cases. If the people who are charged with enforcing the law are not compelled to obey it, regardless of intent, their actions render the law meaningless for the innocent as well as the guilty.
I think it is a terrible idea to allow police officers the use of illegally obtained evidence in court. This calls into question the very security of our legal system - if police officers are allowed to use underhanded means to get evidence that will influence a verdict erroneously, then it's only a matter of time before the courts are corrupted further.
It is very important that police officers are held to certain standards. We need to make sure that they are forced to follow the law, just like the rest of us. If they are allowed to consistently use illegally obtained evidence, then they will continue to do illegal things, since they will know that they can get away with it.
Any evidence submitted in a criminal trial should be obtained legally. Law enforcement should not be able to obtain evidence illegally to use against a suspect in court. The U.S. constitution protects citizens against illegal searches and seizures. These are important rights for the accused in cases to prevent someone from being railroaded into prison. In short, police officers should not be allowed to submit illegally obtained evidence in court.
