By “the Bundy standoff,” I assume you mean the occupation of the Malheur National Wildlife Refuge by Ammon Bundy and his followers? The event that law enforcement took an extremely hands-off approach to because everyone involved was white, and still ended up with one of the participants dead?
If the people who took part in that occupation had been anything other than rich, white, and strongly religious, they would have had tanks rolling in to clear them out.
If you’re talking about the other Bundy standoff, where Ammon’s father Cliven decided he didn’t want to pay to graze his cattle on public lands, lost every court case, and prevented the government from seizing his cattle by showing up with an armed militia… I don’t think a rich white sovereign citizen faces the same level of consequences from their actions as everyone else does.

You’re right, police officers don’t want to die from protestors. That’s why they wear body armor and have armored vehicles, and the National Guard gets deployed if those aren’t enough.
If you pull a gun on a police officer while they’re arresting someone, it’s very likely that you and everyone behind you in the line of fire are going to get shot, repeatedly.
