And ends others by putting big profits in criminal hands.
Following your logic: we shouldn't fight any wars (including civil wars, wars against evil) because, after all, people die and bad things happen.
No, the logic is not that "people die and bad things happen" but that the War on Drugs causes people to die and bad things to happen.
Besides the police only catch maybe 1% of the speeders
They don't catch a hundredth as many drug 'crimes' - which can happen anywhere, whereas speeding can happen only on public roads.
Illegal drugs and illegal immigration are very similar.
Our effort to control illegal immigration has been a failure so why not just “legalize” illegal immigrants. Why even have immigration laws. I am being sarcastic here.
The root of the problem in both issues is the wide acceptance of both by the general population. What proponents of illegal immigrants and drugs tell us is that everyone does it or it doesn't hurt anyone so why not make it legal.
Also, the stigma has gone and actually it is the stigma that it is pretty effective. Looks at the stats for smoking tobacco over the years. Smoking tobacco has dropped off considerably because of the stigma. That stigma is now gone for pot.
It is ironic that smoking cigarettes is banned is some areas but smoking pot is tolerated. That doesn't make a bit of sense and it is clear that pot has political clout and is even encouraged. Why? Because it is medical. It is a medicine and it is good for you. /sarc
