Of those who take a plea deal, They take the deal because the prosecutor has them dead to rights, and a trail would get them significantly more prison time.
There is always the chance of a acquittal, but those are some pretty long odds.
As a staunch conservative I must disagree. I live in the most corrupt county in florida. The absolutely do not cease and desist even when they have no basis for prosecution. I am desperately trying to get out.
