So why are they responsible for most of the crime then? Especially in the US.

It's important to approach discussions about crime and its associations with demographic groups carefully to avoid perpetuating stereotypes or misinformation. Crime rates can be influenced by a complex interplay of socioeconomic factors, including poverty, educational opportunities, access to resources, systemic inequalities, and policing practices, among others. Some studies and statistics may show disparities in crime rates among different demographic groups, often reflecting broader social issues such as income inequality, social disenfranchisement, and systemic injustices rather than inherent characteristics of any group. Focusing solely on certain demographic characteristics without understanding the underlying conditions can lead to misleading conclusions and further stigmatization. When discussing crime, it's crucial to consider the context, including historical and structural factors, rather than attributing crime to specific groups. Solutions to crime often involve addressing these underlying issues, including improving education, access to mental health services, and economic opportunities for all communities.
