The majority of criminal cases in the USA result in a plea agreement. The majority of plea agreements take away a persons right to access to the Courts (taking away Constitutional protects. They claim that you CAN still access in certain constitutional situations but if you try both the lower court and Prosecutor will threaten you with revoking your plea if you pursue an appeal to higher courts. Source: that's how it went down in my situation). Plea agreements were unconstitutional for the majority of the existence of the USA but somehow later became constitutional (even though our system of law are required to respect precedence). While for appearance purposes some limited constitutional rights remain, for all practical purposes anyone convicted via plea has their constitutional rights to the courts removed. In addition, the Federal Court system only allows 14 days from sentencing to file an appeal. 14 days, including days being transferred from court to a Federal Detention Center to your final destination seems extremely unreasonable. Again, it was unlimited until recent history, but it was decided it needed to be 14 days for financial reasons (too many people were accessing their constitutional right to the court and clogging up the system).
