"The future does not belong to those who are content with today, apathetic toward common problems and their fellow man alike, timid and fearful in the face of bold projects and new ideas. Rather it will belong to those who can blend passion, reason and courage in a personal commitment to the ideals and great enterprises of American society." 

Robert F. Kenndey

Here is the Heritage Foundation's "History of Cash Bail," and my assessment of that history (which is not very flattering). 

Here are revised documents discussing Colorado's new bail law, which include the changes enacted by the General Assembly in 2014 through S.B. 212. There is also a handy decision tree created by 
Mike Jones (PJI) and me, which is still relevant.
