Some very odd comments being made on this thread regarding the "challenging" or "having balls to confront", and then a comment about "a sneaky phone call".
I for one have fished for a very long time but would not have the "balls" or confidence to confront someone, but would happily make a "sneaky" call to alert the proper authorities to whatever the indiscretion may be.
I have in the past seen a burglary in process but at the time didn't have the "balls" to confront the burglar and made a "sneaky" phone call to the police who arrived and arrested the person.
Where does it stop, in a perfect world you could just walk up to people and try to "educate" them on their wrong doings, unfortunately in this not so perfect world, "educating" can often lead to a punch on the nose, in this instance I think whoever made the "sneaky" phone call made the right choice and allowed the correct authorities to deal with this guy in the proper way.
If your the kind of person who doesn't mind challenging people committing offences then I applaud you and wish I had your "balls", but the advice from most parties would be to make the "sneaky" call and feel happy you have helped and live to fish another day.
Just a quick story that this reminded me of, on the news recently man (1) saw another man (2) loading shopping into the boot of his car which was parked in a disabled space, man (1) not seeing anything wrong with man (2) and had the "balls" to confront him, outcome was that man (2) had just walked ahead of his disabled wife, man (1) not knowing this and failing to educate properly punched man (2) once, causing him to fall over and bang his head resulting in his death, man (2)s wife arrives shortly after to find people trying to resuscitate her husband and full time carer.
Point of my rant is, it's great having the "balls" to confront and challenge people, but it can all turn very wrong very quickly no Matter how big your "balls" may be or how small the indiscretion may be.
