You hit the nail on the head when you said "they don't have the manpower or money to track and catch all of the criminals" and I think the answer to your question as to why they spend money and time on certain crimes is, quite frankly, it is visible and easy. It is easy to zing people for speeding "excessively" because it is simple and visible. Low level drug dealers / users are easy to zing. Arrest, prosecute, punish, rinse repeat. It is more difficult to do an in depth investigation that takes multiple people, lots of time, etc. and yields questionable results. Sometimes quantity is better than quality. Arrests and citations become stats and that is what the public ends up seeing - "They arrested 500 DUI's last month." No mention that only 5% were over
So the simple answer is - change the law and it won't be illegal anymore.
