For many of you, you will have been subjected to my lesson on the disparity that existed between the mandatory minimum sentences for the use of crack cocaine and powder cocaine. The Fair Sentencing Act of 2010 went some way to closing these sorts of loopholes following Obama pardoning a number of people in the same year for cocaine offences.

The impact of this, at least to some extent, seems to have been an ‘historic’ drop in the number of Americans in federal prisons. This is therefore a really useful example of a President using his Constitutional powers in order to achieve a bill being passed through Congress and the wider impact.
