It looks like he could be! (http://usherald.com/crack-dealer-obama-early-release-murder/)
In FACT, Barack Obama is probably MORE culpable in this incident than Governor Dukakis was in the "Willie Horton" killings back in April of 1987. After all, Michael Dukakis DID NOT initiate the furlough program that resulted in Willie Horton's release, that program had been originally signed into law by Republican Governor Francis W. Sargent in 1972, BUT the original program excluded such furloughs for convicted first-degree murderers.
Horton had been doing time for the October 26, 1974, Lawrence, Massachusetts, fatal gas station hold up, in which Horton and two accomplices robbed Joseph Fournier, a 17-year-old gas station attendant, then fatally stabbed him 19 times after he'd cooperated by handing over all of the money in the cash register. Many (including myself) saw THAT early crime as a racially motivated murder, as Fournier was white...his assailants, black.
At any rate, President Obama DID sign the "Fair Sentencing Act" into law in 2010. That law was set up to reduce the disparities in sentencing between powdered cocaine and crack cocaine...despite the fact that the impulsive violence exhibited by crack addicts which plagued America's inner cities in the late 1980s and early 1990s sparked the passage of laws that doled out stiffer sentences to crack-addicts.
Shortly after his release, Callahan fatally stabbed his ex-girlfriend to death, then murdered her two children, age 7 and 10, in Columbus, Ohio. The horrific crime drew national attention because the children were allegedly murdered to eliminate them as witnesses in the brutal massacre of their 32-year-old mother.
Barack Obama seems at least AS culpable in the Wendell Callahan incident as Michael Dukakis was in the Willie Horton incident. Although there are STILL some who defend Michael Dukakis over the Willie Horton release and claim the Republican attacks on Dukakis over that incident was a misleading, low blow.
Actually, it was a fellow Democrat, AlGore, who first brought the Horton incident to light. George "Pappy" Bush's team merely used it more effectively.
