Lie #24: "Violence in Mexico has increased..."

From Paul Helmke's latest demand for the erosion of American rights for Mexican corruption:

Violence in Mexico has increased since Congress allowed the federal assault weapons ban to expire in 2004.

Except it hasn't. From the AP:

Mexico's homicide rate has fallen steadily from a high in 1997 of 17 per 100,000 people to 14 per 100,000 in 2009, a year marked by an unprecedented spate of drug slayings concentrated in a few states and cities, Public Safety Secretary Genaro Garcia Luna said. The national rate hit a low of 10 per 100,000 people in 2007, according to government figures compiled by the independent Citizens' Institute for Crime Studies.
