Many of the links don't work. The tax numbers are also off. However to completely dismiss this E-mail and state "people who believe anything in it are class-A morons" isn't necessarily the best approach either.
This link was found within one of the links from the E-mail post. This is a report by the House Committee on Homeland Security, Sub-Committee on Investigations:

If you take the time to skim through it pay particular attention to Pg. 25 for information on the sex offenders. Also Pgs. 27-32 on the terrorist estimates and apprehensions. This isn't a money issue. It's a safety and security issue for all Americans, particularly those in urban and lower income areas where drug violence is a major problem.
To summarize:
1) We've got a big problem on the Southern border with much tighter and stronger coordination between U.S. street gangs and Mexican drug cartels
2) Over 130,000 victims of sex crimes per year (many children) are due to illegal immigrant sex offenders.
3) Terrorists are working in Mexico & South America and most likely with government assistance (Venezula) to get into the U.S. through the southern border. In 2005 650 individuals from terrorist sponsoring countries were apprehended attempting to enter the U.S. Considering the rate of apprehesion is less than 20%, it's a conservative estimate to say over 3,000 individuals from terrorist-sponsoring countries are crossing the southern border each year.
