Actually don't bother, I already know it's not true.
The chance of a police officer homicide victimization during a routine traffic stop was quite minimal [I.D. Lichtenberg, A. Smith / Journal of Criminal Justice 29 (2001) 419–428 425] — between
one in 6.7 million and 20.1 million motor vehicle stops.
On the other hand,
1063 people were killed by police during traffic stops in 2015. With 15-20 million traffic stops per year,
that's at best 1 in 19,000 chance of being killed by police at a traffic stop.
So that's 1 in 6-20 million vs 1 in 19,000.
I know you're a former police officer Bert, but you really don't need to keep going to bat for the US police who are a completely different animal to UK police.
Policing over here was (as you know) set up for the public. Policing by consent, Peelian principles, the friendly neighbourhood bobby etc.
The police force in the USA was set up by plantation owners to round up escaped slaves, then to scare off free black people from towns where White people didn't want them. It has always been an organisation to punish and intimidate the population.
You've got very little in common with US police force, you really don't need to keep defending them with made up statements like the ones I quoted. No one thinks police over here are like police over there.
