It wouldn’t show weakness if he actually USED the Guard.
Sigh. Let me explain and break it down to you.
There was no need for Sheriff Clarke to talk to Walker and have the Guard on stand-by. Clarke is the Milwaukee County Sheriff. Other than county parks and buildings, he's got nothing to do with the city of Milwaukee. Not a damn thing. Barrett is in charge of Milwaukee. By calling out the Guard, they are absolving Barrett and Democrats of any responsibility, and if anything further happens, it'll be blamed on Walker, not Barrett.
Seriously, what Walker should have said is that this is a city matter and that Mayor Barrett should be answering all questions.
