Well, regardless of who should shoot who, Sniper I'm glad that nothing happened to provoke that. No matter how much it might be nice to fantasize about blowing away scumbags, no firefight is a good firefight really.
I see people all the time leave their garage doors open all day and sometimes all night, when I see them open after 10 and nobody in the garage I try to knock on their door and let them know (in my neighborhood this is). Fortunately my house tells me when mine is either open for more than an hour and/or it closes it automatically after 8pm unless I tell it otherwise.
