It merely means that race is something that doesn't exist outside of the social conventions of a society, an identity pasted onto oneself or someone else based on superficial and meaningless biological attributes.
Racism can be physically dangerous if 'race' is associated with ethics (be it high or low), such as in this database. But mainly, racism is just stupid (i.e. it obfuscates the real issues).
To think of 'race' as a meaningful category in research underpinning policy mostly proves to an outsider how ingrained racism is in the US.
Where do I claim that racism is a social construct? I said 'race' (not racism).
With this in mind, are police not agents working on behalf of a society? Funded largely (if not solely) by members of that society?
You don't have to look much further than "blue lives matter" to see that police in America are almost looked at as a psuedo-race.

A lot of people think Racism in policing is the real issue. A core one. What do you think the real issues that are being obfuscated are?
