Of course they did it. But it's strictly a misdemeanor affair - violation of hunting permit laws -, so this story really is a tempest in a teapot.
your name.....I remember watching that series on PBS years ago. It was very good.
I don't know what New Jersey's laws are, but that will land you in prison here in Colorado.
Let me see, what to charge them with? Hunting out of season. Hunting without a license. Hunting without a hunter safety card. Conspiracy to violate game and fish laws. Illegal taking of big game. Firing a weapon from a motor vehicle. Loaded weapon in a vehicle. Animal cruelty. Possession of illegally taken big game. Failure to properly tag harvested big game. Hunting after legal shooting hours. Spotlighting big game.
There are lots of people serving lengthy prison sentences around the country for a lot less, a good game warden could come up with multiple charges against these clowns. On the other hand, this is in New Jersey.
