So, since the president is keen on offering instruction, here is what I would advise he teach his Ivy League pals, and anyone else who may find himself unexpectedly confronted by a police officer: You may be as pure as the driven snow itself, but you have no idea what horrible crime that police officer might suspect you of committing. You may be tooling along on a Sunday drive in your 1932 Hupmobile when, quite unknown to you, someone else in a 1932 Hupmobile knocks off the nearby Piggly Wiggly. A passing police officer sees you and, asking himself how many 1932 Hupmobiles can there be around here, pulls you over. At that moment I can assure you the officer is not all that concerned with trying not to offend you. He is instead concerned with protecting his mortal hide from having holes placed in it where God did not intend. And you, if in asserting your constitutional right to be free from unlawful search and seizure fail to do as the officer asks, run the risk of having such holes placed in your own.
The fact that African-American men are disproportionately likely to be put in this position, and that some police officers have this mentality, does a lot to explain the generalized distrust of cops by many people in that demographic.
Meanwhile: This is insane. Most people like and respect cops, and honor the work they do. But it’s a profession that’s honored precisely because the people doing the job correctly don’t do the job this way. Police officers, in the course of duty, subject themselves to extra-normal risk of harm for the sake of the welfare of others. This is the mentality of a foreign occupying army, not a well-functioning police force.
