NO. In my house, unlawfully, trespassing, with not ONE SHRED of GOOD intent? 3:48 a.m. or any other time...
There may be more than one BG and a "warning" may allow the first scumbag that's going downs "friends" to take defensive cover.
I believe in the Spray-N-Wash home defense mentality: IF I have to get my Rem 870 out, after the Model 19, .357, all bets were off to begin with.
NO Warning, and NO Quarter.. if one invades my home....
