Have a look at the above link to see how stupid things are going
VAT (in France) and ramp (in Germany) checks are more and more common (maybe because there are more civil servants) but I've never seen them turn ugly yet.
no demonstrable threat but a broader picture of safety being achieved by control and intervention which we all know is not the case
I believe
that is a more problematic issue. More politicians and civil servants are out to intervene and control simply because it fuels their self-aggrandissement.
Some of the anti-N-reg brigade simply don't realise who their newlyfound bedfellows are. Luckily they are not a majority, but there are politicians (and not the ones you would expect) out there who are supporting the EASA-FCL proposal because it will lead to less people flying (yes they do grasp that) and hence reduce carbon emissions !
Last time I checked painting a G on your empennage did not reduce CO2, so private flying as a whole will be next, at least according to those politicians' agenda.
