As part of the responsibility of being a certificate holder is I feel being whiter than white when it comes to potentially falling foul of a law. If you value your hobby / sport enough (as i do), keeping these certificates is essential. If i were in a situation where my domestic life was in such upheaval to warrant the local police attending to resolve it, i would hope i would have had the foresight to see the potential of this, and stow my guns with an RFD whilst informing the local FEO too. That way I would be safely taking the initiative in the shitty situation and preventing any stupid allegations from the other half. Things have to be pretty bad between a couple domestically for the police to be contacted, he should have seen that coming if he was concerned about his weapons! I know from experience as I have attended many 'domestic disputes' over the years as a police officer. The police will not give the weapons back in a hurry of course until a proper investigation has taken place. I would suggest nothing other than full co-operation in that with honesty is the only way if you ever wish to retain your certificates. Otherwise, to be found out telling porky pies would spell the end of your enjoyment of this sport.
