This part of that RP video really stood out from a 2A standpoint.
Vigilant, observant, law-abiding, gun-owning citizens defend themselves and stop crimes every day before police can respond. That is the source of real security in America: the 2nd Amendment right to defend oneself. The answer is for people to be empowered to protect themselves. Yet how many weapons might these checkpoints confiscate? Even when individual go through all the legal hoops of licensing and permits, the chances of harassment or outright confiscation of weapons and detention of citizens when those weapons are found at a TSA checkpoint is extremely high.
Disarming the highways and filling them full of jack-booted thugs demanding to see our papers is no way to make them safer. Instead, it is a great way to expand government surveillance powers and tighten the noose around our liberties.
