Let's talk a little bit more about this PDF that I pulled this information from. There is a figure here related to jail growth and the article in the PDF explains that this growth in population in California jails is due to the fact that California set up a plan for their prison overcrowding, it had gotten SO BAD that they decided to put a large chunk of their prison population into their jails, which is not what jails were meant for in the first place. 

Why, do you think, for a moment, California's prison population would be experiencing massive overcrowding? The state with the largest number of illegal immigrants and Mexican immigrants descended from illegals is none other than California. The increase in prison population coincides with Mexican immigration. There is absolutely no reason whatsoever that we should let these uncivilized fucking savages into our country.
