Well sorry my rough love is bothering you.
Are you planning on using a silencer? I doubt the neighbors would hear a thing if you did. Even if they did, you can always kill them too.
But then their neighbors would hear it, and it's just be a chain murdering. We don't want that for one person, amirite?
Bah, they'd all die anyway. Just speedin' things up, ya'know?
I live in a rural area, you can hear gun shots hundreds of feet away. Your typical 20 gauge shotgun is very loud within 500 feet. A smaller rifle is audible, but much much quieter.
Get a minigun and muffle it with the bed.
