According to the United States Attorney General, Eric Holder, although
the United States only has 5% of the world's population, we incarcerate
25% of the world's criminals. As a result, he has addressed the American
Bar Association and announced a complete overhaul of the federal drug
prosecution process.
Interestingly, it is estimated that the United States spends $8.7 on law
enforcement for drugs and in 2011, alone, there were the 750,000 arrests
for marijuana related charges.
