But please keep calm, internet, I'm sure the police were in the right.
Nobody who has been arrested has ever been guilty, and filling up every public forum with accusations of injustice the instant we hear any rumor is a mature and effective way to fix the problems in the world.
It is completely reasonable for you to condemn the the police and assume they are guilty of near criminal behavior and bigotry based on the unsupported story someone you don't know personally is posting to Twitter. Most of the time people who just got out of jail are telling the truth, and we should just assume whatever they say is true and start calling for people to lose their jobs.
In fact, every time anyone is arrested then later say they are not guilty, all the police in the entire world are automatically racists.
Since you don't know the person that was arrested (I assume), and you don't know the police who arrested him, you must have some more general way to know that the police here are racists that are profiling him, right? Maybe you know that they are racists because you know all police are racists? Or is it just police in this Country or this State or this City? Maybe 'all police on the night shift' are racist? I don't know how you knew they were racists, but you said it, so I assume you are reasonable to believe it, and there must be a logical way that you figured it out from information you know is true.
As for how you knew this person was innocent, well, since you don't know him, didn't witness any of the events, and only know 'a person was arrested and said it wasn't their fault', the logic from above must apply. You must have made a logical inference that he is innocent. How do you know it?
How do you know that the police here are racists that profiled this person who did nothing wrong? If it is based entirely on the evidence that this person said they did nothing wrong, and that the person tweeted that they were arrested for no reason because the police are racist, well then you must believe everyone who says they didn't do it and that police are racist (or at least the ones that work for Google? or that use Twitter? I'm not sure how you were able to solve this, please let us know.) In that case it would imply that all police are racists, since all police arrest people who later claim to be innocent.
What are you talking about?
Okay but do yourself a favor and look up Austin PD, Art Acevedo, and co. before you rush to their defense. They're not exactly shining beacons of virtue. Frankly, I am confused as to how Acevedo can survive an election in Austin with all the shit he and his deputies have done over the years.
In a different tweet the author said that it was for public intoxication. Austin is a big college town and throwing young guys into the drunk tank for public intoxication is a pretty common thing in these type of towns. And I am willing to bet that most people who are thrown into the drunk tank think they "did nothing wrong".
A reasonable explanation is this guy got a little tipsy and the police thought he was drunker than he was, threw him into a drunk tank to sober up, put a spit mask over his head in case (or because) he was being belligerent or he might puke, then released him once he was clearly sober.
Don't get me wrong, I don't think this is fair treatment. But for anyone who has spent years living in a college town populated by tens of thousands of drunk 20 somethings, it is at least understandable why the citizenry would want police to respond this way. It is also far from a sign that the US is racists as a whole or an (extra) reason we should be afraid of Trump which the author seemed to suggest in other tweets.
