I can't adequately put into words how horrific, upsetting and depressing that is.
It demonstrates again what actual oppression really is. Not the media friendly, urban popular to talk about kind, but the real kind.
Look for the groups who the police don't really work that hard for, and don't really have that much interest in sorting out crimes specifically against, even when the situations are extreme.
Look for the groups the press don't really bother talking about or noticing situations with them that they would be shouting from the rooftops for other groups, sometimes suppressing news that would mention that group in a way that make powerful groups look less good.
Look for the voices that don't make it into interviews or on tv, or if they do they're an unpopular minority given much less airtime and usually there to be shouted down, a token 'balance'.
Look for the groups whose resources are seen as general or enforced to be shared, because that group doesn't matter enough to have things of their own, and it's considered misbehaving on their part to argue and say that they should. Look for the groups scolded for speaking for themselves. Whose boundaries or attempts to stand up for themselves is misbehaviour.
Look for the groups the police are weaponised against in ways other groups don't experience.
Look for the groups that don't get the kid glove, sympathetic gentleness in approach from politicians, media, aren't invited as special guests to give evidence or share experiences to form policy, but are regarded as too beneath contempt to even involve in matters of policy regarding them.
