Thanks you for posting that explanation. Too many here think NBC means what they say it is after wrapping themselves in a flag. That’s now how any law works.
This was the results of work done by the Pennsylvania Supreme court in determining which English statues apply in Pennsylvania. I will remind you that Philadelphia was where the convention was held, and the legal community of Philadelphia (including some of these judges) actually participated in the creation and ratification of the US Constitution.
This is as close as it gets to the horses mouth.
