I mean, even if you were going 65 in a 55 (which is essentially the worst Brady did if he did anything at all), would you accept your punishment if the police weren't even sure the radar guns were calibrated correctly and if they even got the right car? And more to the point, wouldn't the police have dropped the charges at this point, realizing they didn't even have a case?
If it were just a fine I think I'd have just paid up at some point to get the whole thing over with.
But if the police had accused me of a felony, or some other offense leading to jail time, and they had botched every step of the process so badly, there's no way I'd accept a deal that would put that offense on my record, even if I could get off with probation.
Of course, jail time, or having a felony on your record, is far worse than being suspended from work and admitting you cheated, even if it affects you professionally in a very serious way.
