In your opinion is the Miranda warning good or bad? Why?

I think that the Miranda warning is good because the problem was trying to determine what counted as a coerced confession. Well into the 20th century, police officers would beat suspects, or keep defendants in isolation for days, to get a confession. The methods of police interrogation were so diverse, and the effects of isolation, intimidation and defendant ignorance so varied, that appellate courts found it difficult to determine afterward whether a confession had been truly voluntary.
