The issue with Unions is they have to protect all their members. Innocent or guilty, or in one union I know, protect a member, whose goal it was, to be the worst person in the union. (not law enforcement)
Their job is very much like a lawyers.
The case you mention above, while that is one I am watching for information on (court takes time), I don't remember all the rioting and destruction in the street from it!
