Seeing how much debate this string has aroused I think that the following advice that I was given by my nephew, ( Police Inspector ) should help. Get your club representative to speak to the council or park owner with regards warden or parkee patrols, speak to the local police HQ Senior officer or PACT group to see if a staggered visit to the area could be arranged ( Community Police Officers ) As to photos, regardless of proof these are always useful in ID and as to placement of persons, if poss; always switch on the date and time stamp and always deliver the photos to the appropiate authorities ASAP . Get your members to canvass thier local councillors , talk to, and invite your local paper to see how the club use of the water benefits ALL who visiit and use the area. The biggest help you can give these lawbreakers is to do nothing, Despite the media 'Bad News' attitude HELP IS THERE. Lets take back our lives and do something about it...... BigH
