A gunman fired upon thousands of people attending a music festival on the Las Vegas Strip Sunday night, in a brutal attack that is blamed for at least 58 deaths, police say. In the mass shooting and panic that ensued, 515 people were injured. At least one of the dead is an off-duty police officer who was attending the concert.
Editorializing: Interesting how media always emphasize ISLAMIC terrorists, but downplay domestic terrorism as psychologically disturbed individual lone-wolfs.
Not taking a side here, but I think you may not understand the context of the phrasing. At the time it was written state militias were typical and were tacitly used as protection against the possibility of federal government incursion. The freedom of which that amendment speaks of is not freedom from France or Mexico - it is freedom from the possibility of an over encroaching federal government.
