The prosecution has to prove:
1. He had criminal intent.
2. He made the illegal modification for illegal purposes.
3. If this car was previously owned, prove the mod was made by the present owner.
How does a prosecutor prove any of this? Good luck.
Most certainly he will prevail at trial, but its going to cost him $5000 to $8000 in legal fees which he will not be able recover. The States intent of the law is not to necessarily convict but impose pains and penalties to achieve their fascist unconstitutional objectives.
Simple, he screams louder than the next guy.
And they won’t. However an innocent citizen was put to a grand hassle for which he is unlikely to get recompensed by the hassling people.
When wind of the results gets back to the legislature then MAYBE they will put some sanity back into the law.
And in a larger sense, this is another divine lesson in the consequences of tolerating evils (and drugs have little to do with it, surprisingly enough — they are only one of myriad signs of the evils).
