Got to be careful wearing that sort of stuff. Years ago me and a couple of mates picked up some under helmet balaclava's from a motorcycle shop in Deansgate Manchester. Thought we would have a bit of a laugh and wear them back to the car..... turned out a couple of local CID were passing and next thing we were banged up down the local nick for 24 hours and they reckon we were going to turn over a shop as it was close to the shops closing up (days takings etc).
After several rather serious court appearances the judge saw the funny side and chucked it out thankfully! certainly learned our lesson though! and those wooden pillows at the local cop shop have always stayed fresh in memory ; )
