Quite right. Armed trespass should be regarded as a serious matter. I suspect that every police officer I know will agree.
I think that one of the main problems is staffing levels. Not by accident, a lot of poaching goes on at night and at weekends. The police resources by the main at these times find themselves policing the "night time economy", dragged into the town centres to see to our population of well publicised binge drinkers causing criminal damage, picking fights with each other, running off from paying the taxi ride home, getting reported for indecent assaults for pursuing a girl too enthusiastically in some club or going home and having a violent domestic with their partner.
Compare that with the problem of investigating some previously reported poaching incident at a remote farmstead or wood. How can they justify leaving an officer or two in the middle of nowhere at the relevant time in the hope of catching the culprits the next time they come, unable to respond to any other incident? Especially when the poachers will in all probability be having a week off from poaching and getting drunk in that town and causing mayhem there!
So faced with incidents that actually are causing injury or damage, compared to something such as armed trespass, which has the potential to cause injury or damage, with limited resources, it's no wonder that hard decisions have to be made.
That's why it's so important to report every incident. The police are accountable and will seek to address areas where their figures are poor, or be criticised by senior officers. What's more, if you are getting a poor response and wish to complain, then without a history of incidents that don't get any action, how far will that complaint go?
