The decision to run after someone involves a risk-benefit analysis. As you reflexively start running, make the analysis by asking yourself these questions during your first few steps:
- Is this guy a danger to society?
- Is he armed?
- Can I take him?
- Am I alone?
- Will he have buddies?
- How can this go bad on me?
Make these questions instinctive by running through a few simulations every year in various terrains and with various outcomes. These simulations take no equipment, no funds and only a few minutes.
