nobody is talking about shooting at polair. The regs say no drones within 30 metres of people. So anyone doing so is breaking the law and by inference creating a safety hazard. Coincidentally that is about shotgun range. Removing the drone with a shotgun is therefore removing a safety hazard and preventing the commission of any further offence.
A less drastic solution assuming line of sight flying at my place is video of the drone followed by video of the operator and vehicle plus a call to 000.
We live in what is termed a holiday destination and we get a lot of “CUBS” - cashed up bogans with their toys, so a drone incursion is not improbable. We regularly call the police over illegal deer hunting, spotlight shooters, drunken speedsters,unregistered trail bikes etc. as do the neighbors. The police are most attentive at this time of year as we try and prevent them incinerating the neighbourhood, vandalising the infrastructure or killing each other in any number of ways such as throwing butane cartridges into a fire.
