| What does this have to do with what jamesaguilar posted? > No. Surely, something else is broken. Really? There are no other options you can think of? Perhaps the US is simply stricter? I quote from the article this image is from: "Still, it is the length of sentences that truly distinguishes American prison policy. Indeed, the mere number of sentences imposed here would not place the United States at the top of the incarceration lists." So yup, the US is stricter, but it does not have more criminals, nor does it imprison more people. > A graph showing a strange spike There is no spike, this is the result of using a linear graph when it should have been a logarithmic one. (A very common mistake, and also frequently employed when trying to make a point without support in the data.) In this particular graph even better would be to normalize to the population level, but logarithmic is also OK. Either way, if you fix the graph you will find no spike. This graph is better: http://en.wikipedia.org/wiki/File:U.S._incarceration_rates_1... It shows an increase, but no spike. So why the increase? And especially why has it slowed down?

At any particular point in time, there is a greater percentage of the population in prison in the USA than there is in any other nation in the world. We have the highest incarceration rate in the world. It is reasonable to generalize that to "the USA imprisons more people".
Nice non sequiturs with respect to graph scales and lead exposure, though! Our population hasn't been increasing exponentially: why would any population-based statistic be doing so, and why would we want to hide that fact if it were? Also, tetraethyl lead was used at some time in most countries, and indeed is still in common use in those that don't have strict environmental regulations. We still have the highest incarceration rate.
