There is an extremely high conviction rate in US Federal courts. Over 95% of ALL defendants taken to US Federal courts are convicted, leading almost everyone to plea-bargain to a lesser charge and plead guilty.
That's amazing. Why is it so high?
Based on conversations from my buddies from law school who have gone onto become US attorneys, public defenders and district attorneys it seems that it has to do with the allocation of resources
(only the best cases are selected for prosecution by US attorneys), politics
(many district attorneys, etc. are publicly elected) and career considerations (taking only cases with the higher conviction rates leading to promotions versus getting experience to move into private practice).
Perhaps others have some additional insights.
BTW, Hawker, you seem to have no understanding of the actual rules which are applicable with regards to self-incrimination, spoliation of evidence and the contempt power, reason worse than a rock and have no understanding of the law. I am not sure why people keep wrestling with you; you'd think they would figure out the pig likes the mud and they only get dirty.
