89 law enforcement officers were killed in the line of duty in 2019, 48 as the results of "felonious acts."

"X bad thing could happen" is an bad argument because it can be applied to literally any scenario. I could choose not to go get groceries because it's a great idea, until I get hit by a car.

When making policies on serious (and dangerous) topics for a large population, a single death is not a large risk. Even if this policy is wildy succesful, I'd still expect people with mental illness, police, and mental health processions to be occasionally killed in interactions (as they are today).

The point is these are difficult situations and the goal would be to decrease the rate of bad outcomes, likely not eliminate them.

The net deaths might still be lower. 978 people have been shot by police in the US in the past year.

Would you rather try it out on an entire state first? It is low risk compared to the alternative options to experiment.
