how its evolved

In Public Enemies: America's Criminal Past, 1919-1940 by Helmer, William J., and Rick Mattix they talk about how the United States evolved from cops and robbers to the fbi vs the old day gangsters.

One thing that I found that was interesting was that there seems to be times that criminals evolve and the police are just behind them. As the technology of the criminals evolves so does the polices strategies for solving the cases.

When most people think of technology they think of the internet and electronics, but the thing that has impacted the early evolution of technology was the Tommy Gun. The Tommy gun was the first true technological advantage that criminals had over the police. We don't see similar advantages over the police today due to the fact that police look ahead to things that are developing to prepare so they can prepare for them.

Advancements in technology are the main things that cause a change in the police and criminal altercations.
