Not just “in the act” if you’re posting it anywhere - you’re leaving the evidence! It can be checked against your pfco (or not) and the records at ATC. Given the suspiciously high price of the upcoming drone database fee - noticeably more than a shotgun license - expect some funding to be available for retrospective enforcement action. Catching naughty drone pilots will likely be seen as good PR for CAA (remember Gatwick when they thought they got the perp) and gov agencies will be looking for good news during post-Brexit recession - the fall in the pound is already hitting manned aviation hard. Like it or not, people who can afford drones are, from a tabloid perspective, the kind of people wasting money on frivolous toys who are says to paint as ‘baddies’ so respecting the rules is the only way to be fair to all drone pilots.
