Doing away with those rights will increase the number of convictions. Convictions are important. Guilt or innocence isn't. The Seventh Amendment must be disposed of also. Defendants don't deserve a jury trial.
Jury trials slow things down.
After being arrested, defendants should be tortured until they confess, then thrown into prison. Sadaam Hussein controls Iraq by using such tactics. That type of justice will work just as well in this country. Eliminating the Eighth Amendment is also a must. Some would say it is, even though it's not.
