Green and squishy would be pretty much self evident.
But here is a recent incident where a woman didn’t recieve treatment for nearly 5 hours because the officers who discovered her declared her dead.
Whether she might have survived if treated earlier is unknown to us. But the problem was that the first officials on the scene weren’t qualified to make the determination in that case.
If you watch old episodes of Cops, you’ll find that the cops refer to the people they’re investigating as “suspects” - e.g. they will say they are on the trail of a suspected car thief regardless of how overwhelming the evidence is, because it is simply not the job of police to determine guilt (though depending on the jurisdiction, law suspected of breakage, and the evidence available, they can sometimes independently decide to take action such as launching an investigation or an arrest based on probable cause without first checking with a judge, though the judge will eventually become involved if an arrest is made).
