Are the Bill of Rights still appropriate? Should it be

revised? Can they be done better? What do you think?

The Bill of Rights is still appropriate. As of now, there isn't a need for revision as this is how our founding fathers made it, and you shouldn't take away Constitutional rights.

The amendment process is very difficult and time consuming: A proposed amendment must be passed by two-thirds of both houses of Congress, then ratified by the legislatures of three-fourths of the states. The ERA Amendment did not pass the necessary majority of state legislatures in the 1980s.
