I can attest to the risk of meeting a girl with a criminal record. I met a girl a few years a go who, unbeknown to me, had a drugs record and was visited regularly by the police. I met her, paid her, got my right sock off before there was a knock at the door. 20 mins later i was sitting in Dundee police station (not a cell though) the young pc came out and said what I did wasn't illegal as it was the girls own home but he gave me a shitty lecture and it was an unpleasant experience. I walked but I am very careful now!
