That's it in a nutshell. He was jailed because he refused to sign and pay for the $1 peace bond (think restraining order), which would have been acknowledgement that he was legally restrained from protesting. That, of course, is WILDLY unconstitutional - a violation of not only the USC but also of MI law as well.
The ACLU - yes, that ACLU - pretty easily sets aflame the state's case here, in their Amicus brief to the court - which the court then completely ignored.
which goes to show, we’re not longer a nation of laws... just a nation of cute guidelines that will be inflicted upon the political enemies of the ruling party
so much for upholding the Constitution. their word is sh*t. treat them accordingly.
