Militias were necessary at that time due to the very small federal military, hence the inclusion of the term militia in the 2nd Amendment. Essentially, the militia were acting a lot like our regular military does today. However, due to the size of the military since the civil war militias are no longer necessary and therefore the 2nd Anendment is essentially null and void. If the framers intended everyday people to have the unfettered right to possess firearms, then they would have said citizens instead of militia or just left the first part out altogether.
