Almost anything the government does "to protect you" is selective enforcement. It will always be waived for the elites and their chosen golems as much as they can get away with (from entirely to just slaps on the wrist).

Its why its never a good idea to give in to these types of "quality of life" or "protecting the children" laws. It is just handing them one more weapon to hit you with, while the people you are expecting it to hit will just walk right through.
