Personally i think ignorance is bliss, if the customer dont ask i dont tell, i prefer to live catch, nothing worse than going to check tunnels etc and finding the customer upset at "THEIR" pheasant or whatever has met an untimley demise, before you all start blathering on about restricting access etc etc, accidents still occasionaly happen, personally i feel that as a professional, you ,as the law states use the safest method to do the job effectivley. I know that is not exactly the wording, but if you are in the business, and know the law you will know what i am on about.
