Most people who break the law never have a problem with the law.
The only way a criminal act can cause someone a headache is 1- if law enforcement realizes a crime took place and 2- the system chooses to go after you [i.e. DA, judge, etc].
Example: In NH every car is required to have a muffler. No exceptions. But the law says nothing about really ancient cars [like from the 1800s] or electric cars. No cop is going to go "that electric car doesn't have a muffler, I need to give them a ticket." Yet that electric car would be breaking the law each day it goes on the roads. No one is going to go to a car show and ticket a model T owner for not having a muffler the car never came with from the factory.
But, if someone were "being a problem" and pissing off the community by [for example] building a rat rod using a model T and doing burn outs & donuts in a school zone... then a cop might go "we need to teach this guy a lesson" and ticket them for every little nickle and dime thing they did wrong. Including not having a muffler.
Moral of the story: If you don't "be a problem" you can get away with breaking the law. Don't put yourself in a position where people will want to give you a hard time. Meaning if you aren't allowed by the local government to own constrictors: Don't take it outside. Don't let it escape your house. Don't show it to people. Don't talk about having it. Don't let it bite someone who might call the cops [like a neighbor's kid whose parents might freak out and call the police]. Keep small species that no one is going to care about if they do find out about it. I've had cops flat out tell me that they don't care about corns even though they're technically illegal. Why? Because they don't become "a problem."
Think about speeders. Who actually does 65 in a 65 zone on the highway? They don't care if you do 67, 69, or even 70 mph. But if you buzz by a speed trap at 90 you're going to have a ticket. This is probably why people detest speed cameras so much. There is no cop on site to make a reasonable judgment call on who is "being a problem" and everyone who goes 66 or higher gets a ticket.
