I have only ever been pulled over for breaking laws, so it is difficult to justify it as "harassment"- Until the officer goes above and beyond the call of duty: giving me a ticket and getting out of my life.
One time, about 2 years ago, I racked up approx $1000 in fines with a cop behind me: No helmet, run 2 red lights, Ride without due care and attention(Ipod), No headlight, No tail light, and lastly failure to stop when the lights came on. I was also probably close to or just over the legal limit for alcohol, but that never came into it.
I was having my conversation with the passenger officer, and I was being very amicable: no, I didn't have any excuses for running the red lights other than their was no cross traffic at that hour of night, and my headlight/taillight had been recently stolen. I was expecting a fine for at least one of my multitude of offences, and had adopted my usual, friendly "my bad, but I don't really care" attitude. Things were going normally untill they brought up my police record (note: not a criminal record. I have none.) and commented that "a lot of people didn't like me"- At which point I tried to read what was on the computer screen. They didn't like that. especially the officer in the drivers seat, who had repeatedly been interjecting into the conversation with the other officer with little lines like "you need to wear a helmet!" or whatever. At this point, after the computer incident they had directed me to sit down on the curb, and the driver officer said "what you need to do is obey the Motor Vehicle Act", To which I replied, not quite under my breath "What you need to do is F*ck off and Die."...... And I only got one ticket, for running a red light, and it didn't even go through so I never had to pay it. Lucky me!
