The rifles in question, as has been mentioned are legally toys, BUT should NOT be given to kids to go and play with them in the woods.
Just because they are brightly coloured it does not mean that they are for kids or are any less dangerous:
If a lambourghini is bright Orange, it is a lambourghini.
If a lambourghini is black, it doesn't suddenly become a hearse. It is still a supercar, capable of doing supercar things.
Police and parents alike need to get their heads out of the sand and realise that just because the colour of something indiactes that it is for kids, it does not mean that it is!
I must applaud you, Darren, for realising that we are not all young kids and we do want to protect our chosen sport and hobby. And also thank you for not jumping on the 'guns r bad and people who like them are physcopaths' bandwaggon because you have had an issue with a few individuals.
I probably haven't added much here, but there is definately some good, solid advice in this thread.
Cheers
