Because IMPD cannot pretend that it does not have personal responsibility for the moronic laws that exist.
I just all morning listening to people rock on their heels and pull on their labels and talk about aiding and abeting, acting as an agent and conspiracy, oh, and don't forget the "personal responsibility" thrown about when they don't have an answer to your inquiries.
No way it only works one way.
Sure, it's a moronic set of laws and if you ask the police they will likely agree, but as the law is founded on a gun, the police are part of the process.
And your point of view is exactly why LE can never win in the eyes of some people.
This reminds me of a time, I responded to a noise complaint round 1am a few years back. A group was celebrating their grandparents 50 anniversary, and had a live band. A very loud live band that was clearly in violation of city code. The neighbor across the street was seriously annoyed and demanded that I shut down the party. I arrive, talk to the people and ask that they shut down. One of the grandkids asked if they could be allowed to play 2 more songs, even though they had paid for a full hour more. I said sure. I waited for the two song to be over, and thanked the family for hutting down. The next day, I had 2 complaints; one for making the party shut down, and the other from the guy across the street because I didn't make them stop fast enough.
So concerninh a lemonade stand, what if, it's another citizen that doesnt want kids selling lemonade on the sidewalk. And let's say this "grinch" knows that city code prohibits them. What do I say to them "pound sand?" Or do I uphold the law as it is written? 99% of officers aren't looking to stomp on kids having fun; calls like these are typically generated by Mr. "Name Withheld by Request."
