I'd have called for a lawyer straight away, and then sued the police force for wrongful arrest.
And i'd have fought their "drunk and disorderly" charges too, asked em to provide proof of such things. Its stupid that people are charged for things just so they don't get sued for wrongful arrest.
I got questioned and had my details taken by a policeman after i walked to a party when i was 16 and on the way i stopped to checkhow many people where outside, couldn't see anyone....so walked round the corner to my friends house and see if he was coming to the party - he was ill. So when i walked back towards the party hall....he stopped me, asked what i was doing, why i'd looked at the hall then walked off, and why i'd returned.
It was stupid, he didn't arrest me, but he took my details down and said that if i'm seen acting "dodgy" again he'll have to take further action.
Although when sam got mugged (They stole his fone, some beer cans and money) , and i chased them down an alleyway at 11oclock, tracked down which house they where in and had evidence (beer cans that they'd stolen where smashed on the floor outside their house, freshly opened aswell) Called the police.....they didn't even bother to turn up.
