Interesting quote from Barker v. Wingo:
The right to a speedy trial is generically different from any of the other rights enshrined in the Constitution for the protection of the accused. In addition to the general concern that all accused persons be treated according to decent and fair procedures, there is a societal interest in providing a speedy trial which exists separate from, and at times in opposition to, the interests of the accused. The inability of courts to provide a prompt trial has contributed to a large backlog of cases in urban courts which, among other things, enables defendants to negotiate more effectively for pleas of guilty to lesser offenses and otherwise manipulate the system. In addition, persons released on bond for lengthy periods awaiting trial have an opportunity to commit other crimes. It must be of little comfort to the residents of Christian County, Kentucky, to know that Barker was at large on bail for over four years while accused of a vicious 520*520 and brutal murder of which he was ultimately convicted. Moreover, the longer an accused is free awaiting trial, the more tempting becomes his opportunity to jump bail and escape. Finally, delay between arrest and punishment may have a detrimental effect on rehabilitation.
A second difference between the right to speedy trial and the accused’s other constitutional rights is that deprivation of the right may work to the accused’s advantage. Delay is not an uncommon defense tactic. As the time between the commission of the crime and trial lengthens, witnesses may become unavailable or their memories may fade. If the witnesses support the prosecution, its case will be weakened, sometimes seriously so. And it is the prosecution which carries the burden of proof. Thus, unlike the right to counsel or the right to be free from compelled self-incrimination, deprivation of the right to speedy trial does not per se prejudice the accused’s ability to defend himself.
The amorphous quality of the right also leads to the unsatisfactorily severe remedy of dismissal of the indictment when the right has been deprived. This is indeed a serious consequence because it means that a defendant who may be guilty of a serious crime will go free, without having been tried. Such a remedy is more serious than an exclusionary rule or a reversal for a new trial, but it is the only possible remedy.

In Washington, D. C., in 1968, 70.1% of the persons arrested for robbery and released prior to trial were re-arrested while on bail. Mitchell, Bail Reform and the Constitutionality of Pretrial Detention, 55 Va. L. Rev. 1223, 1236 (1969), citing Report of the Judicial Council Committee to Study the Operation of the Bail Reform Act in the District of Columbia 20-21 (1969).
The number of these offenses has been increasing. See Annual Report of the Director of the Administrative Office of the United States Courts, 1971, p. 321.
“[I]t is desirable that punishment should follow offence as closely as possible; for its impression upon the minds of men is weakened by distance, and, besides, distance adds to the uncertainty of punishment, by affording new chances of escape.” J. Bentham, The Theory of Legislation 326 (Ogden ed. 1931).
Very interesting how the Court views this constitutional right on both sides of the social cost spectrum.
