Answer:
Hello, this is a great question to ask!
First lets look into what is considered a crime. Crimes are acts done by individuals that are illegal at that time and date.
A great example of this is was the Prohibition Era, before this Era the selling of alcohol was Legal, but after the act was passed it became Illegal to sell and manufacture alcohol. This is why many began bootlegging alcohol.
So no, you cannot continue to do a crime after it has become illegal.
