Ah yes. blame the cop, not the guilty person. Ever had your back broken? How about whiplash? If you've already suffered whiplash at some point, you'd be amazed at how a small bump from behind, even in a drive-thru, can just tweak it right up.As with most people, you are confused between the letter of the law and the spirit of the law. You can take solace in the fact that the police officer probably doesn't know either.
Then again, those lost in the leftard-o-sphere just aren't into personal responsibility so it's no surprise you have a problem with this.
