It is to do with brexit as it is all part of the nonsense that we have to put up with due to increasing EU influence.
I'm afraid that this is clerly not the case. Should other EU nations follow UK's apparently avowed desire to quit EU, EU would eventually collapse altogether (as indeed some extremist Brexiteers covertly or overtly desire), following which Europe will likely return to a sitation similar to - albeit probably even worse than - that which pertained between the two world wars of the previous century, with every "sovereign, independent state" (to coin a phrase) doggedly pursuing its own interests in broad rejection of the very kind of international / cross-border co-operation which has ensured that no EU nation has declared war on any other one for more than 70 years. That such an end product would be fraught with immeasurable danger should be obvious to an averagely intelligent 12 year old.
You write of "increasing EU influence" but do not specify what this is or what kind of influence you're writing about. Do you believe that EU exerts more and/or more adverse influence over UK than over any of its other member states, such as, for example, those in which such cities as Strasbourg, Brussels, Maastricht and Lisbon are situated?
As I've stated, the powers and responsibilities of ECHR are nothing whatsoever to do with EU and, as such, entirely outside its influence, so anyone or any nation that is subject to the provisions of ECHR are not and indeed cannot be so as a consequence of "EU influence". Council of Europe is not only a quite different and far larger organisation than EU, it has a longer history than EU's oldest predecessor.
You omit to answer why it is you appear to believe that vexatious litigation against UK armed services personnel ought to be treated differently to vexatious litigation against any other UK citizen. Clearly, it should not be so, otherwise government would be conferring - and be seen to confer - a special citizenship privilege upon UK armed services personnel which would be divisive, inequitable, immoral and illegal and it is the last of these considerations that should - and, I hope, will - ensure that no such legislation will find its way onto UK's the statute books. Amerd forces personnel have as many but no more human rights than any other UK citizens.
It would also look extremely suspect were UK's Parliament to pass legislation conferring such privileges upon its military personnel if, in so doing, it were to isolate itself from other European nations who do not do this, for an uneven playing field would thereby be created in which, for example, French, German and UK armed services personnel might be involved on the same side in such interventions but only the UK ones would be privileged by their government's statutory exoneration of them from responsibility for their actions while on duty (and funded by UK taxpayers). I can't imagine that going down too well with military personnel in other EU nations.
"One Polish man killed"? I thought that there were two, actually. In any event, whilst no more condoning those murders than the rape of "white girls" by "Muslims", a due sense of proportionality determines that proper consideration be given to the fact that the murders concerned were the most serious but by no means the sole instances of additional racist hate crimes committed in UK as a direct consequence and in the immediate aftermath of publication of the opinion poll result.
There are also plenty of rapes committed in UK by non-Muslims against girls, boys, women and men of all races, colours and creeds and some, though by no means all, of these are instances of racist hate crimes. Crimes are crimes and, as such, breaches of UK law including human rights law (after all, rape and murder are, amongst other things, breaches of their vitcims' human rights).
Others' remarks here about illegal military interventions and other such interventions of questionable legality, whilst again nothing to do with Brexit, are most pertinent in and of themselves; again, however, although you now imply coyness in your omission to respond to the war crimes issue, you have in the past expressed a desire in principle to witness one particular UK politician being hauled into the dock and tried for such crimes (even though the International Criminal Court is situated in one of those EU nations from which you'd like UK to sever many fundamental connections).
If anyone here feels impelled to initiate new threads about war crimes, illegal or questionably legal military interventions, racist or other hate crimes or indeed any of the other peripheral topics that have from time to time found their respective ways into this thread about Brexit (such as has already happened in respect of the population movement issue), they are of course welcome to do so and would, I believe, be doing this thread a service in helping to keep it on track to discuss Brexit only.
Best,
