A lethal leap, USA, merders per 100,000 people

The provided graph depicts homicide rate in America over three decades starting from 1990. Overall, there was a dramatic decline in the data in a prolonged period, though it showed a sign of picking up in recent years. At the start of 1990, the number of murder cases was at its peak when up to 10. 0 people per 100, 000 were assassinated. However, the figure quickly fell off as within a decade, it dropped from roughly 9. 5 to slightly above 5. 5. Afterward, it remained stable in the following five years, indicating criminal inactivity. Subsequently, the rate continued to decrease further by around 0. 7 in the latter half of the 2000-2010 decade, then bottomed out at below 4. 5 in 2015. From that point, the data started to rise up to precisely 5. 0 half a decade later, which grew concern among the public. This anxiety would only be amplified when the number soared up to merely 7. 0 within only a year, which facilitated governmental actions.
