Police controls and the size of pupils are related because the size of pupils can be an indicator of a person's level of arousal or stress. When individuals are under stress or feeling threatened, their pupils tend to dilate as part of the body's fight or flight response. This physiological response can be detected by police officers during routine controls, helping them assess the emotional state of individuals they encounter. By observing changes in pupil size, police officers can better understand the potential threat level and adjust their approach accordingly. **

Citizens with foreign names may be subjected to stricter police controls due to racial profiling or biases held by law enforcement officers. This can lead to assumptions or stereotypes about individuals based on their name, leading to increased scrutiny or suspicion. Additionally, individuals with foreign names may be more likely to be perceived as outsiders or potential threats, resulting in heightened police attention. These discriminatory practices can contribute to the marginalization and unfair treatment of individuals based on their name or perceived ethnicity. **
