His reports have led to a Congressional inquiry on elder care, saved the lives of people denied adequate medical care, prevented hundreds of low income homeowners from being evicted, and resulted in the imprisonment of dozens of corrupt public officials.

He was the first reporter in America to expose the widespread practice of racial profiling (the Oxford English Dictionary credits Collum with coining the term “racial profiling”). His final assignment was at Ground Zero on September 11, 2001 and the days immediately following the collapse of the World Trade Towers. In fact, Collum’s account of the tragedy was  excerpted in the book, Covering Catastrophe.

Since returning to his roots in Florida he has been writing and contributing reports to PBS.

Drawn from over 200,000 documents and personal interviews, The Black Dragon: Racial Profiling Exposed is Collum's extensive history of racial profiling by the New Jersey State Police to be released in hardcover by Jigsaw Press on September 17, 2010.

Brady's Run, Collum's first novel, was published in eBook and paperback by Jigsaw Press, February 28, 2009. He is currently working on the next book in the Max Brady Mystery series, Et Tu, Brady, to be published by Jigsaw Press sometime in 2011.
