Yes. To be fair, he was a bit of an outcast from the local community anyway, having had disagreements with a number of local worthies, so the local ostracisation was pretty much to be expected, and his helping the British fight against Germany may have simply been an excuse for the locals to make their feelings known, rather than it being a reason.
Government difficulties were at a low level, with police harassment over many issues (some of which were undoubtedly justified, given his relationship with legalities), but which did seem, by all accounts, to amount to victimisation. Whether one regards local police as being "sources from the Government" or members of the local community is something of an open question.
Whatever the actuality (and I emphasise that he was not the most reliable of sources), the reaction he received in the immediate aftermath of the war (in which he joined up to fight against Hitler and Germany, so naturally he spent most of his time out in Burma) turned someone who had actually fought for Irish independence into someone who never had a good word to say about the country.
When people say that those civilians who served in the British forces during the War faced no issues when they returned, well, that's not entirely accurate. It may be the generality, but the reality was a lot more complex than the initial assertion suggested.
