Ad hom??? You are obviously desperate to find some way to evade. The stop sign example is not applicable for the reasons I gave. People don't smoke mj just to piss you off. People don't comply with traffic laws just because they want to be responsible. There is little to gain by running a stop sign and most have no desire to do so.
I understand you want to ponder the fantasy where people just do what the fuck you tell them to do. But it is not reality. Laws have to consider human nature or they will lead to bad results.
Straw man. I made no such claim. Smoking a joint does not cause one to get into a car and play crash up derby. Again, you ignore cause and effect to reach this idiotic point.
If traffic accidents are your concern then the question becomes whether the law effectively deals with that and is narrowly tailored to that end.
WTF RU talking about? I never said you did. The point was clear. Red light cameras are a type of traffic enforcement which has costs that are deemed unacceptable. Ignoring that and just blaming the drivers would be irresponsible.
It is not. I have smoked thousands of times and that never happened. Getting arrested and jailed is the result of enforcing the laws against mj. There is nothing inherent in mj that makes enforcement of the laws against it necessary.
