I'm not from the US but for your question 5 it's the same everywhere.
Gun control is an attempt to take away the right from good standing citizen to have a means to defend their lives and country.
Gun control is a futile way to have peoples who know nothing about guns feel safer.They think if there's more "gun control" (less guns) there will be less crimes. while criminals carry on with their daily routine. What this does is open the door to more crime since a criminal will feel safer in a no gun zone than in a place where carry is permitted. A criminal is someone who does not obey the law so gun control is not for them, therefore, only peoples who obey the law are forced to abide and surrender their guns which negates the very reason for gun control leaving good peoples unarmed at the mercy of criminals.
In short, gun control is just government control, it does nothing to make streets or citizens safer, in fact it does the opposite.
