Over the last several decades, law enforcement officials across the country have pushed very hard to incarcerate those who are convicted on drug charges. U.S. Attorney General Eric Holder recently pointed out that half of the country's federal prison inmates are serving sentences for drug offenses. This startling fact has caused Holder and others to push for sentencing reforms.
In any criminal case, the burden of proof is placed squarely on the prosecution. This is derived from the idea that defendants are considered innocent until proven otherwise. If prosecutors do not provide adequate evidence to meet this burden, then conviction may not be possible.
