Hope you don't mind that I don't just accept your estimates. Please provide the source for that information.
If you figure (conservatively) 20,000 murders in the U.S. per year, then 40 per day roughly translates to 75% of the total. Granted, illegal immigrants commit murder at a rate proportionally higher than the legal population, but that number still appears to be way off.
There are no alternatives from this group to Mexicans planting and picking the lettuce. Just get rid of the Mexicans period.
