Breaking the law is breaking the law, and there is no excuse...but...
Maybe the guys just love to fish and have bass fever, growing up in the area I did, it was tough to find good ponds to fish, and if we ever did fish anything questionable we would always release, but when you love to fish and you see a nice little pond w/o any other sources of water it can be tempting ;D
But, if you are familiar with the area, go talk to the guys and recommend some other spot to fish that you know is legal and try to keep the peace
