Get back to me when we have glassed Chicago. Seriously, there are heavy rat zones, but they are not exclusive to any one religion, nationality, or race. So I just can't get on the glass 'em all bandwagon either as effective or as moral.
Understand the emotion, but cannot get there from here.
Give me the shotgun and you spot 'em then. Let me know if one is still moving after and I'll shoot 'em all. Rat's a rat, red, white, black or blue, if it's got a tail and moving after dark shoot it. Let the buzzards sort 'em out in the morning.
