Castle Doctrine or Stand your ground

[noonereal]

Well we currently have two stories in the news involving people who scream "I am scared for my life" and murder innocent folks.

Both times the fear filled guy was the aggressor and had a gun.

Is it time for the Feds to step in and stop allowing the individual sates from passing laws that allow the slaughter of their own?

If so how?

If not, why do you support such aggressive and lethal laws?
