You've seen all the evidence?
For the defendant, the burden is incredible. Often you're jailed, so no income. Legal costs are high, and if you're middle class, ruinous. Then the nature of most trials is that despite "innocent until proven guilty," the government typically benefits from a favorable reputation in the jury room.
Finally, look at what normally happens when the government and its agents falsify evidence? Normally a slap on the hand, a dismissal of the case, etc etc. The prosecution can treat the discovery process as if it's optional with no real repercussions.
So imho, it's not even close to a fair match. Remeber Richlieu's boast? "If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him."
