The Watchtower says:
He plants murderous attitudes in the hearts and minds of people. For example, 1 out of every 142 children born in the United States will become a murder victim.
The actual source says
...from 1965 to 1992, the homicide rate for the U.S. was 9 per 100,000 people. The first-world democracy with the next highest rate is Canada, with only a quarter of the homicides per capita as the United States. Australia ranks third, with only a fifth of the U.S. number. If the murder rate in the United States continues, 1 out of every 142 children born today will be murdered. Even if the lower rate of 6 per 100,000 that the United States experienced during the 1990’s continues, nearly 1 out of every 200 newborns will eventually be murdered.

The murder rate in the USA has substantially dropped since that cherry picked high range. The murder rate in the USA is now 5 per 100,000 per year. If the current rate continues then one person in 266 will be murdered if you take an average lifespan of 75 years.
This means that if you are born in the USA you have a 99.62% chance of NOT being murdered.
Well it wouldnt be the watchtower if it wasnt time to panic.
