The incident which took place in August as reported by the Weekly Standard; 
1-"He was handing out flags to anybody who wanted them...The SEIU guy came up to him and said, "Wis an n-word like you handing out these flags?"
2-"Kenneth didn't't say anything to the guy. Before Kenneth could even say anything or act in any way shape or form, the SEIU representative punched him in the face." Big Govt
3-"He went to the ground. Subsequently, two other SEIU representatives or members, however you want to say it, jumped on top of him, yelled racial epithets at him...kicked him, punched him."
The crime has been firewalled by both news media and .orgs (Media Matters...). Ken Gladney was beaten and hospitalized. Even so, charges have yet to be filed.
Big Government report reports, "Yesterday, Pastor Himes provided powerful, and courageous, witness to the union violence he and his wife saw in St. Louis on August 6th. They provided strong testament to the union attack on Kenneth Gladney."
If the SEIU attackers are not guilty, why is the organization paying For Mr Gladney's medical bills? Political higher-ups will provide legal counsel as well.
Consider the effort here to eliminate the right to free speech and ask how the legislation will seal it. These people are simply enforcers, ready to be on call bills are passed.
