This is a tough one, BUT we all know there are unscrupulous cops and unfortunately there are a very few who will single out a person and continue to harrass him for whatever reason. So like any other crime it should go to court and evidence should have to be presented and proven before a conviction can result. As far as I'm concerned the "Charter of Rights" has nothing to do with, it's a farce that was dreampt up by a raving lunatic. I guess there are instances where "street racing" could be hard to prove. If two motorists on a four lane highway are driving abreast above the speed limit are they street racing? For the reasons I've mentioned a conviction should result in a severe sentence, maybe 18 months in jail and a 10 year driving prohibition. That would probably put a damper on it.
First off, that's the whole point of the Charter of Rights, it guarantees us that we are protected from this sort of thing. That's why it's written down! Without your 'lunatic', there would be no reason that we could claim this sort of thing was wrong.
Second, the whole 'street racing' thing is deceptive; it's a name that Ontario uses for the laws on driving, simply so that they get the emotional reaction from people who think it has to do with young punks drag racing on the streets. It doesn't. Read the list of offences.
