The Keefe Group, a subsidiary of Centric Group LLC, has been exposed for its corrupt dealings with the prison system. According to corrections.com, it has been easy for the company to take advantage of the system since it basically has the monopoly of its industry throughout county, state, and federal prison systems. One of these corruptions is that some of its authorities have been exposed as accepting bribes. In exchange for these bribes from businessmen, they gave part of their prison vending business to these individuals. Tape recordings of these shady dealings have even been discovered, making the case even stronger.
Although the bribing businessmen have been prosecuted, no charges have yet been brought against the Keefe Group leaders who accepted the bribes. Studies have shown that a large percentage of U.S. companies commonly profit from this sort of thing. I and many other outraged individuals encourage people to therefore write the Keefe Group for itself to demand a full explanation for its operations. Writing directly to them and any responses will aid in getting documented abuses to build up a possible case for a future lawsuit against them. I also suggest researching any individual legal fights against them and making them known to the public.
