In the 2019 district council elections, pro-government candidates won 42% of the vote (but much fewer seats due to the non-proportionality of the electoral system) https://en.wikipedia.org/wiki/2019_Hong_Kong_local_elections...

So while the government is only supported by a minority, it is a quite large minority.

Those police officers most likely have a support network of friends and family who think they're doing a good job.
