so what did you omit from the story that got those random as locals to call the cops who in turn called the arm defenders squad armed with Assult rifles and tasers to raid your place which you share with your dear old gran,
sounds like an unplanned trip to shoot up the countryside
not too many roads left that don't have someone living on them, and it is hard at night to ascertain what is behind your target or how close housing is
what made them chase you?
time will tell, you may get stung for the cost of the callout at the least or possibly a loss of firearms license
in todays world of driveby shootings, recent standoffs with cops etc random shots in the middle of the night near housing will usually provoke a call to police
