Ah yes, efficiency is the ultimate goal, right comrade? What is a little state threatened violence (there is no way to say that 10s of years of forcible incarceration is not a threat of violence, there is no way to say that an increased security classification due to sentence length, and therefor incarceration at a much more violent prison, is not a threat of violence) for the waiver of 2 little rights (plea's include a waiver of the right to a trial and the right to an appeal)? Imagine the efficiency if we could allow the state to use violence to get 'citizens' to volunteer to waive their right to remain silent? So much efficiency comrade. It's not like Constitutional rights are important part of this country, we should treat them like China treats the ones enshrined in the Chinese constitution, just look how efficient that makes China, right comrade?
