“Mexico quadrupled the federal police presence Thursday in a western state after a cartel killed 20 officers and troops in the boldest revenge attack ever mounted by drug traffickers against the government. The government deployed 1,000 more federal police to the cartel’s home state of Michoacan, bringing the total to 1,300, Public Safety Department spokeswoman Veronica Penunuri. They will be backed by at least three Black Hawk helicopters and three armored vehicles.” (07/16/09)
