A couple of amazing stats:
Worldwide spending on legal services amounts to about $250 billion a year, some two-thirds of it in America. (via the Economist)
The United States has the highest prison population rate in the world, some 714 per 100,000 of the national population. This is over ten times(!) the rate of Denmark or Finland. (via World Prison Population List)
In total the US has 2.09 million prisoners and 23% of all prisoners in the world. ( via Prison Policy)
That just blows me away. The US has 5% of total world population, 23% of all prisoners and 2/3 of all legal services.
