It all boils down to the definition of the word crime. A crime is injury to a person or property. If there is no victim, how can there be a crime?
Anything else is revenue collection.
For the most part I agree.
I do think some regulation of behavior to prevent injury is needed. I don't believe all of it is either necessary or effective. For example, speed limits in residential areas, school zones and hospitals clearly prevent predictable injuries and I'm okay with having those laws and having them enforced, even if I might break them myself from time to time. If I get caught, then, I'm willing to own that behavior and pay the fine.
Speed limits on highways don't necessarily do so and I would change those to "speed ratings" (as in "this road way is rated to allow safe travel up to 100mph" type warnings). Getting a ticket for going 80 in a 65 area bothers me, especially when that might be the safest rate to match surrounding traffic. But that is the thing, many of our highways increased the speed limits based on citizen input because we have a process to influence the system. And if you don't care for the way politicians handle that process, you have the right and ability to get yourself elected and handle it the way you want.
Also, things like "gun free zones" or other administrative restrictions that aren't really enforceable day to day and so are imposed as a reaction an event do not have the intended deterrent affect. I think eventually we will see many of our zero tolerance laws changed--they certainly don't make a lot of sense to my millennial generation kids.
I'm also a proponent of changing what happens with the revenue collected by fines and civil asset forfeiture. None of that would go back to the departments collecting it and none would be held even by the local municipal governments. I would put it all into funds for victims recovery, addiction treatment, child welfare etc. We are seeing several states change these laws right now because citizens are influencing their politicians to make this right.
Finally, vice crimes are a reflection of old thinking and I would prefer they be moved into the realm of regulated commerce.
So, I'm not blind to the fact that some of our laws maybe over reaching and may not be having the effect they originally had in mind. Or maybe they are having the effect and cities, towns and states are enjoying ill-gotten gains. But, that doesn't mean I don't believe we need some level of regulation to keep things moving along nicely.
Having said all of that, I can happily approach any law enforcement officer and have a polite conversation. I can even respond to them politely and will respect their directions if they are reasonable and within the law. I don't even require all the information if it is clearly an urgent situation and I might be in the way. I understand what they are trying to do and will treat them with courtesy when I engage with them. If they treat me otherwise, then I'll deal with that afterwards.
