I believe you misunderstood me. Text is a very poor vehicle for innuendo.
Consider, a police man pulls you over for speeding. The driver shows disrespect in some form or another. The policeman knows that the radar provides evidence in a recorded, quantifiable and verifiable manner. But his ears produce none of the above.
So for reasons of demonstrating power (ego) he reports the car as being loud, and impounds the car. No evidence is required .... none, zip, nada. It's his word against yours. If he is black and doesn't like whites; impound the car. If he is white and doesn't like blacks; impound the car. If you remind him of someone he hates, he's in a foul mood, you have a nicer car than he does ... whatever.
No evidence, no witnesses, no record of the violation; you are giving TOTAL strangers the ability to stop you at will, effectively STEAL your car; thereby forcing you to stay in a hotel/motel and bail your car out of bondage ... and the distinct possibility exists that you did NOTHING at all.
Now I have known a few police officers in my day. Many are honorable, trustworthy, honest and upright citizens performing a Hero's job. But there are a great many High School 'Bullies' who cravely hide behind their badge, so they can abuse people while using the badge as a shield. There are also the craven lowlife who are unworthy of respect, so they take a job as an officer and use the badge to prove a point.
Now, you are saying that I should support giving any person with a badge the authority to impound my car, without the benefit of due process, witnesses or any kind of evidence, proof or recording instrument?
I wouldn't trust my mother with that sort of power.
The officer will testify to what he heard/saw, that is the evidence. I realize there are some rouge coppers out there. Now if he lies and impounds your vehicle that is wrong. Due process comes in when you appear at the impound hearing and tell your side. I'm sure where you live the police department must have some type of office that looks into police misconduct. My suggestion is contact them with your complaints. As for using a recording instrument to obtain evidence, that is probably a question of economics, some departments not being able to equip vehicles due to lack of funds. So I guess you are stuck with having to trust that the police wont put a case on you.
