Does the Miranda warning impede crime prevention? Why or why not?

The Miranda warning impedes crime investigations and also makes it more difficult to get confessions from suspects. However it does not impede crime prevention. The Miranda right is only read during arrests but it does not protect a suspect more than just requiring the presence of a legal counsel. It is read for the purpose of preventing a violation of the fifth amendment. The Miranda rights does not extend to any acts that might affect government and police efforts in crime prevention.
