This could really be hard on the Police. Imagine they arrest a person with a protected characteristic. That person, some random passing stranger, anyone who learns about it could allege that the arrest, the complaint that led to the arrest was motivated in part by hatred.
I think ScotGov is relying too much on people being reasonable. The emotionally incontinent, the most victimised, mischief makers and grifters aren't reasonable but they can fake it.
Fortunately for them Tiffany Scott (Gawd rest his soul) is no longer with us. He'd have had such fun with this!
Taking the complaint, deciding it's not reasonable. Telling the complainant it's not reasonable, dealing with that. Dealing with appeals. These all take time. Even if it's initially deal with by some sort of call centre triage, this has to be staffed and paid for. And in all this noise there will be genuine, serious cases that will be lost. Not to mention other crimes that will inevitably be neglected.
