The police seem to resent

Mind reader, eh?

[null and void]

Nope. If I could read their minds and they resented I wouldn't say "seem to resent".

Perhaps the somewhat more awkward phrase: "the police officer's behavior was indistinguishable from what it would have been had he resented the citizen defending his own life rather than waiting for his betters to show up shoot the bear themselves and recover what remained of his body" would have suited you better?
