Remove the warrant check portion of traffic stops and suddenly they become much much less risky and just normal community policing. But adding that 'the person may have a warrant and the US justice system is happy to hand down 10+ year sentences (which are basically life sentences, you aren't getting a life back after 10 years) every traffic stop by choice become much more high risk.

Policing shouldn't be done via traffic stops. Traffic stops should be done via traffic stops.
