However, laws have to be enforced clearly with no "what if....".
Where did you come up with that nonsense? There are an infinite number of "what if" situations that a creative mind could think up and ponder how the law should be enforced in such a scenario. Here's a couple for you....
The law says brake lights have to be red or orange, and that both brake lights have to be the same color.
What if there's a small hole broken out of one lens, allowing a small amount of white light to come out?
What if the lens is broken but covered with a red tape?
What if both are red, but a slightly different shade of red?
What if the difference in shade can't be seen by 35% of people?
What if the officer is colorblind and pulls you over mistakenly? Is that a legal stop? Is the marijuana in the trunk admissible? Or is it fruit of the poisoned tree?
What if the driver is colorblind and couldn't see the difference in shade?
What if the colorblind driver can't see the difference between red and orange lenses?
That's alot of what-ifs, and that's just for mundane traffic matters!
The law cannot differentiate between providing a service to some law-abiding, tax-paying citizens and not to others.
Yes it can, and it has since the beginning of time! It makes me recall an incident about two months ago where I refused service to a group of law abiding, tax-paying citizens based on the fact that one of the members of their group was being an asshole toward one of my staff. Are you going to tell me that I broke the law? HA!
