Is destroying someone’s drone illegal?
Edit: [It is only legal if federal officers deem it a ‘credible threat’ (as per the FAA Reauthorization Act)], otherwise it could be as unlawful as throwing rocks and breaking the employee’s parked and vacant car windshield.
But honestly, I wouldn’t complain to the railroad about it, they could come down on your nuisance complaint like a loose caboose ( hee hee, like the pun?).
A friend of mine got a flat tire at a railroad crossing due to a spike sticking out of the ties, and he sent them a letter asking for reimbursement for a tire. They sent him a bill for damaging the railroad crossing!! Seriously, they could use your photo against you and have their own police give you a trespassing citation or something, it’s just not worth it.
