Have you considered that in some situations, prudence takes precedence over speed? As I have said before in other discussions, in real life you don't wrap up a case in a neat little package in one hour like they do on television. A lot of times there is more at play than just pointing a finger at a suspect, putting them in jail, then let things run their course. There is evidence that needs to be processed and there are questions that need to be asked and answered. Sometimes these things take time. Another thing is that a prosecutor only gets one bite of the apple in bringing a suspect to trial so it is vitally important that they take the care needed to get it right the first time. If they proceed to arrest and trial without their ducks in a row, the perpetrator can go free. And I for one would rather they err on the side of caution and get it right rather than to let the criminals go free because of our freedom from double jeopardy.
