Everything I've heard the Wisconsin senate and governor threaten so far has been petty, hollow, or, worse yet, inconstitutional. Threatening to fine 100$/day for being missing is inconsequential to their incomes, even at 40 business days missing (two calendar months). Theatening to put the state police on them is also hollow, as they're not even in the state police's jurisdiction. On top of that it could be inconstitutional, which will only return to hurt them.
I don't even know the real issue at stake here. Just the tactics I hear being used seem ... wrong.
