they just can mate. My friend had an argument with his missis, she'd had 3 bottles of wine, ended up neighbours coming round, continued in the street. police turned up. She told the coppers he'd hit her, even though there was no evidence, he was sober and she was ruined, and not a mark on her, they locked him up for 'her safety' even the copper said it was ridiculous but they couldn't leave him there. Then while the investigation was ongoing, emptied his gun cabinet. Shite but thats just the way they deal with things.
