Do you know why the United States citizens have the right to bear arms?
Because the founding fathers recognised that the citizenry may have to overthrow their government should it become oppressive as did the government of George III in 1776.
It was a consideration of the founding fathers. As they constructed it, they were cognisant of the fact that one day it might be necessary to tear it down.
p.s. If you want to know what words mean, you should look to your dictionary, not your television. The dictionary hasn't been entirely corrupted (yet. although that definition for liberty is starting to look a little 'iffy').
