to fear being killed by a police officer more than a drunk or distracted driver.

Or to fear contracting or being diagnosed with a disease.

I use irrational because youth under 25 are being killed daily by people not in uniform, and this can happen regularly no more than 10min away from where most people live, yet we're more afraid of the police, based on stories that occur 2,000 miles away (not saying that police incidents don't occur in Baltimore, just speaking of national headlines).
