[Mark17]

Aren't there security cameras at the stations? I know that the trains themselves are equipped with cameras. ODD that footage of the perp is being suppressed.

I think there are, but I don't think it is odd at all, to suppress this stuff. I am not much into conspiracy theories, but in this case, I believe there IS a conspiracy by many, to suppress the knockout game thing.

The very existence of a campaign of hate using a “knockout game” whether coordinated or just for bragging rights, should trigger a series of federal civil rights violation investigations (including the police departments that are suppressing reports of the incident and refusing to prosecute the guilty).
