If you are referring to the oath to obey orders for their job, close to 98%
Oath to constitution would be 2%
We already saw this happen during Katrina
cops went house to house with lists taking guns
there is video of people loudly complaining that their rights were being violated
not a single cop cared
more recently during covid,
cops had no problems arresting people for going to work, or church
they had no problem shooting people with rubber bullets for being out of their homes
the cops that would follow those orders aren't 50%, 70, 80 or 90, but closer to 98 or 99%
the amount that will refuse won't even be a blip
