What exactly do you disagree with about the right to a trial within a reasonable period of time?  I assume that if you are ever charged with a criminal offence, you would not appreciate having that charge hanging over you indefinitely.

Yes, of course, absolutely, delays caused by defence counsel scr*wing around should stop the countdown but otherwise, what's the problem?  If the Crown can't get to trial within a reasonable period of time, it shouldn't charge in the first place.
