A member of the Black Lives Matter protesters argues with a police officer as they shut down the main road to the Minneapolis St. Paul Airport following a protest at the Mall of America in Bloomington, Minnesota December 23, 2015. REUTERS/Craig Lassig Race-relations between the police and black citizens is a huge topic of conversation in America right now.

Athletes are refusing to stand for the national anthem in protest over police killings of unarmed black men, the presidential candidates were asked about the issue in their debate on Monday. And on Tuesday, police near San Diego fatally shot another unarmed black man within minutes of responding to a mental-health-related call.

With this subject in mind, we bring you this story of what an ordinary black family can face when they need the police.

Take for example this series of tweets from by Tristan Riddell, who is best known for his Nerd Party network podcasts The Senate Floor and Nerd Nuptial. For his day job, he works as a videographer/video editor at Northwestern University.

"One of my favorite students had his car stolen last night. He's a 17 year old black male. Thought it would be a good idea to call the cops.

Groceries in hand he checks his LoJack app first and can see that its moving down the road. Cops arrive and immediately frisk him.

They ask him if he's on drugs. He tries to tell them that he just wants his car back.

He shows them on his phone exactly where his car is. They don't believe him so they put him in the squad car and take him in. They process him and take his fingerprints.

He gets to call his mom and she raises hell. After a long time they let him go.

They then allow him to go get his car and the window is broken in. It was exactly where the app said.

This never would have happened to me because I'm white. He called the cops asking for help and got treated like a criminal.

Just because he's black and could afford a fancy car."

Here are the final two tweets in the story:

We reached out to the student who has, so far, not responded to our questions. Riddell has not revealed his identity nor said what city and police department where this occurred, except to reveal that it happened in Illinois.

Although Riddell's tweets mention LoJack by name, if the story is true then the subject was probably using some other app instead, as LoJack does not have a consumer app for tracking stolen vehicles.

Northwestern is located in the Chicago suburb of Evanston however the Evanston police have confirmed to Business Insider that this incident did not occur in Evanston.
