Peaceable Journey: Is there an implied allowance?
A recent question about a "peaceable journey" through a state in the USA got me thinking: Is there an implied allowance for someone to transport one's weapons through a state without issue, so long as the rules in that state are followed with respect to (a) not being loaded and (b) being secured in a locked case/trunk for the duration of the journey? Or, is the simple answer that it varies from state to state?
Guess: That it's absolutely an issue of state's rights, and that each state's firearms laws can vary considerably.
Does anyone know for certain? (Links, laws.)
Federal law trumps state or local
The Federal law cited above allows people moving from state to state to pass through a location with restrictive firearm laws and legally transport their gun. I believe the motive for the law was to prevent the type of harassment that sometimes happens in places like New Jersey or New York, when honest citizens who were simply travelling through the state would be victimized by the local police.
The harassment can still happen, but the citizen who follows the Federal rules will ultimately prevail in court.
