Well in most states if the Police go on an illegal strike the governor will have the State Police take over and call up the state's National Guard.
This is a case of maybe both sides being asses. The Governor of WI might have been too draconian in the wording of the bill but it was a very stupid move on the Dem's part to leave the state and the unions to escalate the issue the way they had.
Here in Nevada with 14% unemployment when the unions tried to play hardball they lost the public and had to take cuts and now layoffs. With the economy in the shape it's in this is a no win situation for state union workers.
