Why do we wait until someone dies? LEO’s carry lethal force every day, and exercise authority in ways that can easily intimidate even the most law-abiding. They should be tested daily, with zero tolerance. One and done.
I disagree. First off that would be quite expensive, second off, daily testing practically guarantees that every officer will have a false positive or two throughout his or her career.
The same standard as locomotive engineers and bus drivers is sufficient.
Oh, and lethal encounter includes traffic accidents as well as shootings tazerings and beat downs.
