Sorry to say this but it's a good old case of tell nobody nowt all guns should be kept in a gunsafe out of the way even if being repaired just because they're air guns doesnt make them any less lethal also if he's told his bosses who else might he have told ie mates down the pub local scallys etc I would be more worried about having my house robbed than pen pushers IMO as has been said before though an air gun unless fac does not require a licence so you should be ok on the council side of things but get a nice big cabinet for your guns ;-)
