So, .308 for home defense. Farm /Forest where you're defending against man or predator with distant neighbors, yes, with great care. Urban/City neighborhoods probably to much rifle. But remember the L.A. Korean neighborhoods riots and just recently the murdered families in the Israeli Kibbutz's and the murdered concert goers of Israel. Who would have expected to be murdered from Para Gliding Hezbollah military? and now foreign military sympathizer's pouring into in our streets, in our college neighborhoods. Unknown quantities pouring in over out boarders. Find the people in your circles of people who are combat veteran and TRAINED for this kind of thing ( which I am NOT) ask and listen. Should you find yourself in such a bad spot, Pray up to God for wisdom while calling for the Sheriff, the rest is your choice and good judgment.
